Detail of Function
O
Chip enable output for tuner PLL
[ I ]
Reset output for HD Radio
Use prohibited, always set to input (HiZ)
Data is taken in with PSV port set to High 20ms after resetting is cancelled
(U model)
Model detect 1 (net)
O
Synchronous data input for tuner PLL
O
Asynchronous data input for HD Radio (U model)
O
Synchronous clock output for tuner PLL
O
Synchronous data output for tuner PLL
O
Asynchronous data output for HD Radio (U model)
MCU
O
TUNER Mute output
H: Mute
Always Mute when tuner is not selected
MCU
Commonly used with ZONE mute being in use when selecting FM/AM band
O
TUNER TUNED input
Pull up to +5S
O
TUNER STEREO input
Pull up to +5S
O
+5S ON/OFF control
* +5S is OFF in the sleep mode so as to reduce wasteful power consump-
tion when set to low power consumption (Mute circuit, pull up, etc.)
* Shifted to sleep mode about 10 seconds after SYSTEM OFF
O
Power relay control
O
Protection excess current detect
O
ZONE2 SP relay control
Z2RY and SPB must not be High at the same time
O
Surround back SP relay control
Center & surround SP relay control
O
O
Interrupt input for power down detect
O
MAIN power/ZONE2 power /SCENE1-4SW interrupt
Pressed SW is judged by ADKEY0 and ADKEY1
O
Remote control pulse input
O
Front SP B relay control
O
Front SP A relay control
±B voltage control by impedance selection
O
Power consumption is reduced because B voltage becomes Low
Low (Relay OFF, B voltage High) when set to 8 ohm, High (Relay ON, B
voltage Low) when set to 6 ohms and temperature rises
O
DC TRIGGER output
O
Pure direct LED
O
Reset output for FL driver
O
Rotary A for input selector
O
Rotary B for input selector
O
Rotary A for TONE/PROGRAM
O
Rotary B for TONE/PROGRAM
O
O
Rotary A for volume
Asynchronous communication data input for SIRIUS radio
Serial communication is 5V TTL/CMOS logic level
Pull Down by 100k-ohms
O
Rotary B for volume
