Detail of Function
EEPROM access for back-up/I2C
Remote control pulse input 2
Remote control pulse input 1
Reserve
Dock discrimination / Used to discriminate DOCK by AD value. 10k_ pull-up should
be included on the microprocessor side in advance.
Destination discrimination by AD value
AD power amplifier output LEVEL detect 1
AD power amplifier output LEVEL detect 2 (reserve) / Pull-up on AMPPOW P.C.B.
side
AD temperature detect 1
AD temperature detect 2
AD temperature detect 3
Main microprocessor reset control (H/L control while main microprocessor is elec-
trically charged) / Control according to the power control time schedule
Open setting available for power relay off sequence
Interrupt into main microprocessor / Pull-up on DSP P.C.B. side
/ Match the timing to fix to Low during stand-by period to the timing to set
VNP_N_RST to Low.
Communication between microprocessors
Asynchronous data output (sub -> main)
Communication between microprocessors
Asynchronous data input (main -> sub)
Full mute control (Video) reserve
Debugging mode (sub-microprocessor single operation) / Enters the debugging
mode when set to Low.
/ The terminal is treated so that it is pulled up to +5M at 47k and the jumper menu
is provided for GND.
