I2C PROGRAMMING/READING SEQUENCES

A correct turn on/off sequence respectful of the diagnostic timings and producing no audible noises could be as

follows (after battery connection):

TURN-ON: PIN2 > 7V --- 10ms --- (STAND-BY OUT + DIAG ENABLE) --- 500 ms (min) --- MUTING OUT

TURN-OFF: MUTING IN --- 20 ms --- (DIAG DISABLE + STAND-BY IN) --- 10ms --- PIN2 = 0

Car Radio Installation: PIN2 > 7V --- 10ms DIAG ENABLE (write) --- 200 ms --- I2C read (repeat until All faults

disappear).

OFFSET TEST: Device in Play (no signal) -- OFFSET ENABLE - 30ms - I2C reading (repeat I2C reading until

high-offset message disappears).
