Function
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.)
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.)
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
I/O _{switches 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 0 V.
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. (Connected when an LA9250M is used.)
Note: The same potential must be connected to all the power supply pins (V_DD, VV_DD, L/RV_DD, and XV_DD).
