Notes)
* PCMD is an MSB first, tow's complement output.
- GTOP is used to monitor the frame sync protection status.(High:sync protection window released.)
- XUGF is the negative pulse for the frame sync derived 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 XPLCK and the EFM signal transition point coincide.
: GFS goes high when the frame sync and the insertion protection timing match.
- RFCK is derived with the crystal accuracy. This signal has a sycle of 136 s(during normal-speed.)
* C2PO represents the data error status.
- XRAOF is genarated when the 16K RAM exceeds the +4F jitter margin.
