6. Chroma input signal : As for the PAL signal, the burst swings such as 130 and 225 every one hour. Chroma describes the phase caused when the burst occurs at 135. As for the NTSC signal, the burst occurs constantly at 180. The figures below are based on the phase of NTSC. When a PAL signal is generated, adjust the phase and then enter signals. The item common to both PAL and NTSC is the PAL signal. For those other than this, the measurement must be performed for each individual signals.

Description of Read Status
X-RAY X-ray detection circuit is activated with thyristor by means of the threshold voltage from Gnd to 1Vbe. Simultaneously with activation of thyristor, the H drive pulse is stopped and the thyristor output is sent to BUS. BUS Read enables reading of the real-time state of thyristor. To cancel thyristor operation, it is necessary to lower VCC once. 1HEX : Detected POR The POR detection circuit cannot be used in LA76832 and should be ignored. The circuit is operating and performs detection with HVCC = <3.6V. At the same time, the memory for Bus Read is set. (Memory is set at power ON.) To reset the memory, it is necessary to set the ON/OFF control bit to zero once. Since the BUS Read Status and ACK are not returned simultaneously with detection, BUS cannot be read at detection. Failure of ACK return may be useful at detection. For example, the BUS communication start may be timed with ACK at power ON. RF. AGC IF. LOCK V. TRI ST/NONST 0 : RFAGC OUT = "L", 1 : RFAGC OUT = "H" For details, refer to the Application Note. Ignore because this does not function fully at present. Returns the output of V trigger detection circuit in VCD. The internal memory status is renewed at every A. 1HEX : Detected Returns the output of V trigger detection circuit output in VCD standard (262.5 H) and NON standard. Returns in real time the FF output whose mode is determined in VCD. 1HEX : Standard For details, contact us after referring to the Application Note. H. Lock KILLER Detects the phase of FBP and Hsync, integrates the output, and detects in about 40H after HVCO LOCK. 1Hex : Locked Returns the color killer condition. However, the time constant is long, so that about 1V cycle (16 ms) is necessary for detection. Pay attention to the wait for change in the device status. Returns the real-time status for BUS Read. 1HEX : Killer ON Color sys Returns the color system status. Refer to the color system table in the register truth table. The read status is the same as for BUS Write.
