user?s manual u16647ej1v0um 22 chapter 3 notes on target system design to debug the target system with the IE-V850E1-CD-NW connected, a circuit to connect the IE-V850E1-CD-NW is required on the target system. for details, refer to the user?s manual of the target device.
chapter 3 notes on target system design user?s manual u16647ej1v0um 23 3.1 connection circuit example the following shows a connection circuit example of the target system required when connecting the ie-v850e1- cd-nw. for details, refer to the user?s manual of the target device. figure 3-1. connection circuit example v dd v dd target device ie connector (IE-V850E1-CD-NW side) dck v dd dms ddi ddo drst flmd0 reset dck dms ddi ddo drst flmd0 reset v dd gnd cautions 1. keep the pattern length as short as possible. (do not exceed 100 mm.) 2. v dd of the ie connector is used for detecting whether the target board is powered on. 3. the dck, dms, ddi, ddo, and drst pins may function alternately as general-purpose ports. therefore handle these pins in accordance with the specifications of each target device. 4. make sure that the signals driven from the IE-V850E1-CD-NW and the signals generated on the target system do not conflict. 5. flmd0 is connected only when the target device incorporates flash memory. 6. reset may be required when both of the following conditions are satisfied. ? ? ? ? drst of the target device has an alternate function ? ? ? ? the IE-V850E1-CD-NW is connected to a target system that only uses the poc reset function, without using the reset pin function 7. supply the on-chip debug power supply for v dd .
chapter 3 notes on target system design user ? s manual u16647ej1v0um 24 3.2 interface signals this section describes the interface signals. 3.2.1 drst this is the reset input signal for the on-chip debug unit. this is a negative logic signal for initializing the debug control unit asynchronously. barring a problem arising from the specifications of the target device, pull down this signal to low level. figure 3-2. drst pin connection example 74lv125a drst IE-V850E1-CD-NW 22 ? target device v dd target system drst upon detection of v dd of the target system following integrated debugger startup by the IE-V850E1-CD-NW, the drst signal changes from low level to high level to start the on-chip debug unit of the target device. the change of the drst signal from low level to high level also resets the cpu. when debugging is started by starting up the integrated debugger, cpu reset always occurs. 3.2.2 dck this is the clock input signal. this signal supplies a 20 mhz clock from the IE-V850E1-CD-NW. the dms and ddi signals are sampled in synchronization with the rising edge of the dck signal in the on-chip debug unit, and the data ddo signal is output in synchronization with the falling edge of the dck signal. barring a problem arising from the specifications of the target device, pull up this signal to high level. figure 3-3. dck pin connection example 74lv125a dck IE-V850E1-CD-NW 22 ? target device v dd target system v dd dck

chapter 3 notes on target system design user ? s manual u16647ej1v0um 26 3.2.7 flmd0 this is the flash mode signal. it is used only when the target device incorporates flash memory. the flash self-programming function is used for the download function for downloading to the flash memory using the integrated debugger. the flmd0 pin must be made high level during flash self-programming. there are two methods for controlling the flmd0 pin from the IE-V850E1-CD-NW. either one can be selected for use. <1> control from IE-V850E1-CD-NW connect the flmd0 pin from the IE-V850E1-CD-NW to the flmd0 pin of the target device. in the normal mode, nothing is driven from the IE-V850E1-CD-NW. when, during a break, the download function, etc., of the integrated debugger is executed, the flmd0 pin from the IE-V850E1-CD-NW is controlled to be high level. barring a problem arising from the specifications, pull down the flmd0 pin to low level. figure 3-6. flmd0 pin connection example <1> 74lv125a flmd0 IE-V850E1-CD-NW 22 ? target device v dd target system flmd0 <2> control from port connect an unused port of the target device to the flmd0 pin. the same port pin (port in figure 3-7) can be used with no problem to realize the flash self-programming function in the user program using a similar method. barring a problem arising from the specifications, pull down this pin to low level. perform settings to make the port pin high level prior to executing the download function and make the port pin low level or high impedance after executing the download function, through the integrated debugger console. (for details, refer to the id850nwc integrated debugger ver. 2.51 or later operation (windows based) user?s manual (u16525e) .)
