Chapter 2 Operation
2.1.13 Operation Panel
The clock synchronization OPCLK of NHDC LSI is used to input the switch data and output the LED data and LCD data
through the operation panel control LSI (IC1: BU6152S).
A 2-byte (15 bits + 1 even parity bit) command (OPDATAOUT-P) is transmitted to the LSI (BU6152S) in synchronization
with the OPSCLK-N signal. The LSI decodes this command and when it is found to be legal, returns a 2-byte command
response back to the NHDC LSI which includes data on Switch information, LED status, LCD status receive command
ACK/NAK and 1 odd parity bit.
Any transmission errors found cause the command to be reissued after the transmission of the OPSQCR-N signal.
