Notes: PCMD is an MSB first, two's complement output.
GTOP is used to monitor the frame sync protection status. (High: sync protection window open.)
XUGF is the negative pulse for the frame sync obtained from the EFM signal. It is the signal before sync protection.
XPLCK is the inverse of the EFM PLL clock. The PLL is designed so that the falling edge of XPCLK and the EFM signal transition point
coincide.
GFS goes high when the frame sync and the insertion protection timing match.
RFCK is derived from the crystal accuracy, and has a cycle of 136µ (during normal speed).

C2PO represents the data error status.
XRAOF is generated when the 16K RAM exceeds the ±48F jitter margin.

CD TEST MODE
1. How to Start the CD Test Mode
While pressing the ENTER key, connect the AC power plug to the wall outlet.
When the test mode starts up, all indicators light.
2. How to Exit the CD Test Mode
Either press the POWER button or press any button other than CD or disconnect the AC power plug.
* If a disc has not been inserted, the CD test mode does not function.

Mechanism
*1: If the focus search continues for 10 minutes or longer, the driver IC heats up and the protection circuit starts working.
Because of this, there can be a case that a machine does not work at all. In such a case, turn off the main power once.
After it is cooled down, restart the machine.
*2: If the FF button or the RWD button is kept pressed, the gear can be damaged because the sled motor keeps rotating even
