LC78622E
Ports set to be output pins can output high or low levels independently. The lower 5 bits of the 1 Byte data
correspond to those ports. The bits in the data correspond to CONT1 to CONT5 in order starting with the LSB of the
1 Byte data. This command is a two-byte command. (RWC set once)
dn =1... Sets CONTn to be an output pin
dn =0... Sets CONTn to be an input pin

Both in normal- and double-speed playback modes, the 16M pin buffer outputs the 16.9344 MHz external crystal
oscillator 16.9344 MHz signal. The 4.2M pin supplies the LA9230M, LA9231M or LA9240M system clock, normally
outputting a 4.2336 MHz signal. When the oscillator is turned off both these pins will be fixed at either high or low.

DOUBLE-SPEED PLAYBACK
The clock that is used as the time base is generated by connecting a 16.9344 MHz oscillator element between these
pins. The OSC OFF command turns off both the VCO and crystal oscillators. The system control microprocessor can
issue double-speed or normal-speed playback command when the application implements double-speed playback
system.
