3. VCO monitor; Pin 21: PCK
PCK is a monitor pin that outputs an average frequency of 4.3218 MHz, which is the VCO frequency divided by two.
4. Synchronization detection monitor; Pin 22: FSEQ
Pin 22 goes high when the frame synchronization (a positive polarity synchronization signal) from the EFM signal
read in by PCK and the timing generated by the counter (the interpolation synchronization signal) agree. This pin is
thus a synchronization detection monitor. (It is held high for a single frame.)
5. Servo command function; Pin 64: RWC, pin 66: COIN, pin 67: CQCK
Commands can be executed by setting RWC high and inputting commands to the COIN pin in synchronization with
the CQCK clock. Note that commands are executed on the falling edge of RWC.
