The ports that are set to output pins then they can independently output either high or low levels. The lower four bits (bits
2 to 5) of the single 
byte 
of data correspond to the respective ports. Starting with the second bit from the LSB end of this
single byte of data, the bits correspond to CONT2, CONT3, CONT4, and CONT5. The command uses a two-byte
command format (RWC1 set).

Clock Oscillator  Pin 60: XIN, Pin 59: XOUT
By connecting a 16.9344 MHz oscillator to these pins a clock is generated that serves as the time base.
The OSC OFF command is a command to stop the oscillation of the oscillator and the VCO oscillation. Moreover,
depending on the command, double speed playback is also possible.
*
When structuring a double speed playback system, connect a 16.9344 MHz oscillator between the XIN (Pin 60) and
the XOUT (Pin 59), and set the playback speed using the double speed playback command.
*
Recommended crystal/ceramic oscillator constants.
The load capacitance Cin and Cout will have different requirements depending on the actual print circuit board used, and
thus it is necessary to perform verification testing on the use print circuit board. Consult the oscillator manufacturer.
16M and 4.2M Pins  Pin 41: 16M, Pin 42: 4.2M
When using double speed/normal speed playback mode, a 16.9344 MHz signal will be output from the 16M/NGJ pin
after the external crystal oscillator 16.9344 MHz. A 4.2336 MHz will be output constantly from the 4.2M pin, forming a
LA9230/40 Series LSI system clock. When OSC is off, both terminals are constantly either high or low.
