Additionally, CONT1 to CONT5 ports can be set up individually to function as control output pins with the PORT
OP-E/D SET command. The ports are selected using the lower 5 bits of the 1Byte data. The bits in the data
correspond to CONT1 to CONT5 in order starting with the LSB of the 1Byte data. This command is a Two- byte
command. (RWC set once)

Ports set to be output pins can output high or low levels independently. The 8 bits of the 1 Byte data correspond to
those ports. The bits in the data correspond to CONT1 to CONT8 in order starting with the LSB of the 1 Byte data.
To use CONT6 through CONT8 as output ports, the port functions must be set with the $D9 and $DE commands.
This command is a two-byte command. (RWC set once)

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.
21. 16M and 4.2M Pins; Pin 60: 16M, pin 61: 4.2M
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 LA9240M or LA9241M 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.
