FUNCTIONAL BLOCK DESCRIPTIONS
Command Decoder and Command Interface
This module determines whether the input data is interpreted as data or command. Data is directed to this module based upon the input of the D/ C pin. If D/ C is high, data is written to Graphic Display Data RAM (GDDRAM). If D/ C is low, the input at D0-D15 is interpreted as a Command and it will be decoded and written to the corresponding command register. Reset is of the same function as Power ON Reset (POR). Once RES receives a negative reset pulse of about 1us, all internal circuitry will be back to its initial status. Refer to Command Description section for more information.
7.2
MPU Parallel 6800-series Interface
The parallel interface consists of 8/16 data pins (D0 - D15), R/W( WR ), D/ C , E( RD ) and CS . R/ W ( WR ) input High indicates a read operation from the Graphic Display Data RAM (GDDRAM) or the status register. R/W( WR ) input Low indicates a write operation to Display Data RAM or Internal Command Registers depending on the status of D/ C input. The E( RD ) and CS input serves as data latch signal (clock) when they are high and low respectively. Refer to Figure 9 of parallel timing characteristics for Parallel Interface Timing Diagram of 6800-series microprocessors. In order to match the operating frequency of display RAM with that of the microprocessor, some pipeline processing is internally performed which requires the insertion of a dummy read before the first actual display data read. This is shown in Figure 3 below.

The parallel interface consists of 8/16 data pins (D0-D15), R/W( WR ), E( RD ), D/ C and CS . The
CS input serves as data latch signal (clock) when it is low. Whether it is display data or status
register read is controlled by D/ C . R/W( WR ) and E( RD ) input indicates a write or read cycle when CS is low. Refer to Figure 10 of parallel timing characteristics for Parallel Interface Timing Diagram of 8080-series microprocessor. Similar to 6800-series interface, a dummy read is also required before the first actual display data read. 11

MPU Serial 4-wire Interface
The serial interface consists of serial clock SCK, serial data SDA, D/ C and CS . SDA is shifted into an 8-bit shift register on every rising edge of SCL in the order of D7, D6, ... D0. D/ C is sampled on every eighth clock and the data byte in the shift register is written to the Display Data RAM or command register in the same clock. No extra clock or command is required to end the transmission.
7.5
MPU Serial 3-wire interface
Operation is similar to 4-wire serial interface while D/ C is not been used. The Display Data Length instruction is used to indicate that a specified number display data byte(s) (1-256) are to be transmitted. Next byte after the display data string is handled as a command. It should be noted that if there is a signal glitch at SCK that causing an out of synchronization in the serial communication, a hardware reset pulse at RES pin is required to initialize the chip for re-synchronization.

Graphic Display Data RAM (GDDRAM)
The GDDRAM is a bit mapped static RAM holding the bit pattern to be displayed. The size of the RAM is 128 x 176 x 2 = 45,056bits. Figure 5 is a description of the GDDRAM address map. For mechanical flexibility, re-mapping on both Segment and Common outputs are provided. For vertical scrolling of display, an internal register storing the display start line can be set to control the portion of the RAM data to be mapped to the display. Figure 5 shows the case in which the display start line register is set at 30H. For those GDDRAM out of the display common range, they could still be accessed, for either preparation of vertical scrolling data or even for the system usage.

LCD Driving Voltage Generator and Regulator
This module generates the LCD voltage needed for display output. It takes a single supply input and generates necessary bias voltages. It consists of: 1. 3X, 4X and 5X DC-DC voltage converter: The booster output at VCC equals to n time VCI where n is the booster ration. The VCC voltage must be greater than 2V + VL4 or 2V + 1/2 VL7. Please refer to application notes for details. 2. Voltage Regulator Feedback gain control for initial LCD voltage. Internal resistors are connected between VSS and VR (internal contrast voltage reference), and between VR and VL7. These resistors are chosen to give the desired VL7 according to the following equation:
R2 V L 7 = 1 + x Vcon R1
where:
and
(63 - ) Vcon = 1 - x Vref 210
Vref is the internally generated reference voltage (1+R2/R1) is the software programmable IRS value is the software contrast level from 0 to 63 3. 4. 5. 6. Bias Divider There is an on-chip bias divider inside the chip selected by software which generate all VL2~VL7 levels automatically. Contrast Control Software control of 64 voltage levels of LCD voltage. Bias Ratio Selection circuitry Software control of different bias ratios to match the characteristic of LCD panel. Self adjust temperature compensation circuitry Provide 4 different compensation grade selections to satisfy the various liquid crystal temperature grades.

7.10 Level selector
Level Selector is a control of the display synchronization. Display voltage can be separated into two sets and used with different cycles. Synchronization is important since it selects the required LCD voltage level to the HV Buffer Cell, which in turn outputs the COM or SEG LCD waveform.
7.11 HV Buffer Cell (Level Shifter)
HV Buffer Cell works as a level shifter which translated the low voltage output signal to the required driving voltage. The output is shifted out with an internal FRM clock, which comes from the Display Timing Generator. The voltage levels are given by the level selector, which is synchronized with the internal M signal. For a panel with N rows and M columns, the optimal LCD driving voltage are given as:

7.15 Data Read / Write
To read data from the GDDRAM, input High to R/W( WR ) pin and D/ C pin for 6800-series parallel mode. Low to E( RD ) pin and High to D/ C pin for 8080-series parallel mode. A complete data read cycle must issue two clocks to read both First Byte and Second Byte from GDDRAM. No data read is provided for serial mode. In normal mode, GDDRAM column address pointer will be increased by one automatically after each complete data read cycle. Also, a dummy read is required before the first data is read. See Figure 3 in Functional Description. To write data to the GDDRAM, input Low to R/W( WR ) pin and High to D/ C pin for 6800-series parallel mode. High to E( RD ) pin and Low to D/ C pin for 8080-series parallel mode. A complete data write cycle must issue two clocks to write both First Byte and Second Byte to GDDRAM. For serial interface, it will always be in write mode. GDDRAM column address pointer will be increased by one automatically after each complete data write cycle. The column address will be reset to 0 in next data read/write operation is executed when it is 127.

COMMAND DESCRIPTIONS
Set Lower Column Address [00~0F]
This command specifies the lower nibble of the 7-bit column address of the display data RAM. The column address will be incremented by each data access after it is pre-set by the MCU and returning to 0 once overflow (>127).
8.2
Set Higher Column Address [10~17]
This command specifies the higher nibble of the 7-bit column address of the display data RAM. The column address will be incremented by each data access after it is pre-set by the MCU and returning to 0 once overflow (>127).
8.3
Set Master/Slave Mode [18~19]
This command is used in Cascade function, programming the driver into slave mode. The Osc clock and M clock (frame) will be received externally to synchronize the COM/SEG waveform.
8.4
Set Internal Regulator Resistors Ratio [20~27]
This command is to enable any one of the eight internal resistor (IRS) settings for different regulator gains when using internal regulator resistor network. The Contrast Control Voltage Range curves is referred to the following formula:
R Vout = 1 + 2 *Vcon R 1
63 - Vcon = 1 - * Vref 210
, where Vref = 2.1V

Set Power Control Register [28~2F]
This command turns on/off the various power circuits associated with the chip. All the function blocks can be turn-on independently, but a 10ms-time must be wait between turn ON the Regulator and Divider.
8.6
Set Display Start Line [40~43]
The second byte sent specifies which row of the RAM is to be displayed in the first row of window defined by Set Upper/Lower Window Corner commands. Vertical window scrolling is achieved by setting this value from 0 up to window row number + 15. The content outside the Upper and Lower Window Row will not be affected. Refer to Page 21, example 5 for more information.
8.7
Set Display Offset [44~47]
The second byte sent specifies the mapping of display start line (COM0 if display start line register equals to 0) to one of ROW0-159. COM0 is mapped to ROW0 after reset.
8.8
Set Multiplex Ratio [48~4B]
This command switches default 160 multiplex modes to any multiplex from 16 to 160. The chip pads ROW0-ROW159 will be switched to corresponding COM signal output. Examples were given in the RAM map table. If the input value is not a number of 160, 128, 64 or 32, the higher number of mux will be applied to the COMx pins and the RAM content of the additional lines will be masked out from the display. Thus the actual display effect will be equal to the input value. Suitable bias ration must be set by using Set LCD Bias command after this command is issued.

These commands are used to define the upper left corner of the window for vertical scrolling. After POR, these registers are set to (0, 0). The actual window position will be offset by the Set Display Offset command.
8.12 Set Lower Window Corner (bx, by) [62~63]
These commands are used to define the lower right corner of the window for vertical scrolling. After POR, these registers are set to (127, 159). These registers must be smaller than the multiplex ration as defined by Set Multiplex Ratio.
8.13 Set DC-DC Converter Factor [64~67]
Internal DC-DC converter factor is set by this command. For SSD1854, 3X to 5X multiplying factors could be selected.
8.14 Set Contrast Control Register [81]
This command adjusts the contrast of the LCD panel by changing VL7 of the LCD drive voltage provided by the On-Chip power circuits. VL7 is set with 64 steps (6-bit) contrast control register. It is a compound commands:

8.16 Set Segment Re-map [A0~A1]
This commands changes the mapping between the display data column address and segment driver. It allows flexibility in layout during LCD module assembly. Refer to Figure 5.
8.17 Set Entire Display On/Off [A4~A5]
This command forces the entire display to be illuminated regardless of the contents of the GDDRAM. This command has priority than the "Set Normal/Reverse Display" but lower priority than the "Set Display On/Off" command.
8.18 Set Normal/Reverse Display [A6~A7]
This command sets the display to be either normal/reverse. In reverse display, a RAM data of `0' indicates an "ON" pixel while in normal display; a RAM data of `0' indicates an "OFF" pixel. This command has lower priority than both "Set Display On/Off" and "Set Entire Display On/Off".
8.19 Set Power Save Mode [A9]
This command is to force the chip to enter Sleep Mode. The internal oscillator and LCD power supply will be turn off when enter to such mode.
8.20 Start Internal Oscillator [AB]
After POR, the internal oscillator is OFF. It should be turned ON by sending this command to the chip.
8.21 Set Display On/Off [AE~AF]
This command is used to turn the display on or off, by the value of the LSB. It has the highest priority over other commands regarding the display effect.
8.22 Set Page Address [B0~BF]
This command positions the page address of 0 to 21 possible positions in GDDRAM. Refer to Figure 5. During 16-bits write operation, the last bit of the page address is ignored, D0-D7 always writes to even page and D8-D15 always writes to odd address. 29
