I/O
Remote controller identifier input (3). This pin functions as an output pin set to the low level
during resets (when the *RES pin is low) and for a few milliseconds after the *RES pin switches
I/O
to the high level. Therefore, applications that will set this pin high must connect an external pull-
up resistor to this pin.
Monitor for C1, C2, single, and double error corrections.
O
(Note that this output is only provided in test mode. This pin outputs a low level during normal
mode operation) (No connection)
Outputs a 7.35 kHz synchronizing signal that is generated by dividing the crystal oscillator
output.
O
(Note that this output is only provided in test mode. This pin outputs a low level during
normal mode operation) (No connection)
O
Audio mute output signal.
I
Remote controller signal input.
Remote controller identifier input (2). This pin functions as an output pin set to the low level
during resets (when the *RES pin is low) and for a few milliseconds after the *RES pin switches
I/O
to the high level. Therefore, applications that will set this pin high must connect an external pull-
up resistor to this pin.
O
Left channel D/A converter output.
—
D/A converter power supply.
—
D/A converter ground. This pin must be connected to 0V.
O
Right channel D/A converter output.
I
Close switch detection input. A pull-up resistor is built in.
I
Remote controller identifier input (1). A pull-up resistor is built in.
O
Connections for a 16.9344 crystal element.
I
—
Crystal oscillator circuit power supply.
I
IC reset input. Applications must set this pin low temporarily when power is first applied.
I
DRF input.
