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... Outputs high level signal from the CONTn pin set to output
dn =0... Outputs low level signal from the CONTn pin set to output
20.
Clock Oscillator; Pin 45: X
IN
, pin 44: X
OUT
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 microcontroller can issue
double-speed or normal-speed playback command to specify the playback speed when the application implements
double-speed playback system.
Recommended oscillators
CSA-309 (C = 8 pF) from Citizen Watch
CSA16.93MXZ040 (C = 15 pF) from Toyama Murata Seisakusho
CSA16.93MXW0C3 (with built-in capacitor) from Toyama Murata Seisakusho
21. 16M and 4.2M Pins; Pin 60: 16M, pin 61: 4.2M
The 16M pin outputs the 16.9344 MHz external crystal oscillator 16.9344 MHz buffer signal. The 4.2M pin supplies
the LA9230M, 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.
