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
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.
(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.
(Note that this output is only provided in test mode. This pin outputs a low level during
normal mode operation) (No connection)
Audio mute output signal.
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
to the high level. Therefore, applications that will set this pin high must connect an external pull-
up resistor to this pin.
Left channel D/A converter output.
D/A converter power supply.
D/A converter ground. This pin must be connected to 0V.
Right channel D/A converter output.
Close switch detection input. A pull-up resistor is built in.
Remote controller identifier input (1). A pull-up resistor is built in.
Connections for a 16.9344 crystal element.
Crystal oscillator circuit power supply.
IC reset input. Applications must set this pin low temporarily when power is first applied.
DRF input.
