PIN NAME
FUNCTION
INTERFACE CIRCUIT
11
12
Port 1
Port 2
Input pins (input ports) for peripheral IC control
signals (digital signals).
Apply (supply) to this pin output returned from
peripheral ICs which are controlled by
microcontroller via this IC. The return output
contains data on operating status of peripheral ICs
controlled by microcontroller (eg, operating status
and operating mode set by microcontroller).
13
W-ch Offset
Rejects offset of woofer channel direct current bias
voltage.
Connect capacitor between this pin and GND.
14
15
16
Port 3
Port 4
Port 5
Output pins (output ports) for peripheral IC control
signals (digital signals).
Output microcontrol signals (I
2
C bus line signals) to
peripheral ICs from these pins.
Microcontroller sets operating status (eg, operating
mode) of peripheral ICs using these output signals.
Pins are open-collector ; output levels are H and L.
17
Port 6
Functions same as port 3 (pin 14), port 4 (pin 15)
and port 5 (pin 16).
Output levels are H, M and L.
