3. VCO monitor — Pin 21: PCK
This pin monitors the 4.3218 MHz (on average) signal created by dividing the VCO frequency. In 2

speed playback
mode, the frequency becomes 8.6436 MHz.
4. Sync detection monitor — Pin 22: FSEQ
When the frame sync (a positive sync signal) read from the EFM signal by PCK and the timing (interpolated sync
signal) generated with a counter match, this pin outputs a high level. Thus this pin functions as a sync detection
monitor. Note that it holds the high level for a single frame.
5. Servo command function — Pin 64: RWC, pin 66: COIN, pin 67: CQCK, pin 18: PCCL
The LC78628E instructions can be executed by setting RWC high and inputting the command to COIN in
synchronization with the CQCK clock. Note that the command is executed starting at the fall of the RWC signal.
