Asynchronous communication data output for SIRIUS radio
Serial communication is 5V TTL/CMOS logic level (U, C models)
SCENE button LED control 0
SCENE button LED control 1
SCENE button LED control 2
Chip enable output for FL driver
Data is taken in with PSV port set to High 20 ms after resetting is cancelled
Model detect 0 (RX/HTR)
DOCK power control output / H: ON, L: OFF
MIC detect
SP output level detect for AD power limiter
Refer to the limiter setting table
AD protection power amplifier DC detect
Refer to the protection setting table
SIRIUS radio power enable output
L: Power ON HiZ: Power OFF
Used as input port because SIRIUS power turns ON if set to Low Fix when in
the Standby/Sleep mode (U, C models)
AD Dock ID judgment
The type of Dock being connected is judged and operation is changed
Synchronous clock output for FL DRIVER IC
Synchronous clock output for OSD IC
Include 1k-ohms in the series to make applicable to pure direct
Synchronous data output for FL DRIVER IC
Synchronous data output for OSD IC
Include 1k-ohms in the series to make applicable to pure direct
AD KEY1 for taking in AD value
AD KEY0 for taking in AD value
AD protection power voltage detect1
AD protection power voltage detect2
CIDEO power control
Low when VIDEO OFF
Set according to specifications of pure direct and return to Low Fix when in
Standby/Sleep mode
AD temperature detect
Refer to the protection setting table
AD destination discrimination
Data is taken in when resetting is cancelled
iPod accessory power detect
Becomes Low while iPod is booting (for about 2 seconds)
Identification executed when booting is judged as completed
Asynchronous data input for iPod
Standby --- All Zone power OFF, Master ON
MCUSleep --- Low current consumption state at Master OFF
