Description
Capstan FG input pin.
Drum FG input pin.
Drum PG input pin.
Playback CTL pulse input pin.
Composite sync signal input pin.
External input pin to FRC capture unit.
(Port H)
8-bit output port ; Medium withstand voltage (12V) and high current
(12mA), N-ch open drain output.
(8 pins)
Remote control receiving circuit input pin.
14-bit PWM output pin.
(Port I)
7-bit I/O port.
I/O port can be
specified by bit
unit.
(7 pins)
Timer/counter, CTL duty detection, 32kHz
oscillation adjustment output pin.
Input pin to request external interruption and non
maskable interruption. Active when falling edge.
