Detail of Function
ON/OFF control of the +5SPC power supply
(L = ON / H = OFF: for reduction of standby power)
Fixed at Low usually
The standby power is reduced (MCUSleep) by setting at Hi after the
procedure required for the standby setting is completed
When changing to the Standby mode, set at Hi after the ending
procedure is completed
(HI) for flash writing
I2C bus data of TUNER communication
I2C bus clock of TUNER communication
TUNER TUNED input
TUNER STEREO detection input
Chip enable of electronic VOLUME control
Serial clock of electronic VOLUME control
Serial data of electronic VOLUME control
Sound switch of DAB and TUNER
L: DAB, H: TUNER (FM)
Head phone MUTE control
Low = MUTE ON
MAIN MUTE control
Low = MUTE ON
Speaker relay control
Hi = Relay ON
iPod Audio signal detection
Power relay control
AC IN detection circuit
Pull up to +5M by 100 k-ohms on the SUB TR circuit board
POWER AMP current protection is detected
* R-840 used as current protection as well
If specifications are the same, the current protection and DC
protection are monitored by AD
Low = normal, Hi = abnormal
The PRI logic 5V is made with +B and Zener
Power supply protection detection 2
Power supply protection detection 1
Temperature detection
POWER AMP DC protection is detected
The PRI logic 5V is made with +B and Zener
The PD resistance is for fixing at Low in the normal state
iPod Play/Pause SW detection
Connecting 91pin: AD5: I-KEY0
Usable for the direct play by TUNER PRESET Up/Down
The key is discriminated by checking the AD5 value after an
interruption is detected
POWER DET detection of SYSTEM (PLAYER)
Effective distinction of player's CPU
Hi = player CPU effective
RECEIVER CPU state signal
Hi = Receiver CPU effective
SYSTEM communication receiver CPU to player CPU
SYSTEM communication player CPU to receiver CPU
Encoder phase detection input for input selector
Encoder phase detection input for input selector
Destination distinction
R-840/NS-BP300
