Function
Random mode indieator output.
(Low : random mode , high , modes other than random mode).
Synchronizing signal detection output. Outputs a high level if the synchronizing
signal detected from the EFM signal and internally generated synchronizing signal
match.
Driver mute control signal output. (Low : driver mute , High : driver not mute).
Digital power supply for pins.
C2 error signal monitor.
(Note that this output pin is only provided for testing. Mount a external resistor
between VDD5V in order to monitor this signal but connect this pin to the digital
ground in normal mode operation.)
Audio mute control signal output. (Low : audio mute , High : audio not mute)
Remote controller signal input.
Remote controller identifier input (2). A pull-down resistor is built in.
(Open : "0" . Connected to VDD5V : "1")
left channed 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.
(Connected to digital ground : "0" . Open : "1")
Connections for a 16.9344MHz crystal oscillator element.
Crystal oscillator circuit power supply.
LSI reset input. Applications must be set this pin low temporarily when power is first applied.
DRF input.
