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 frame sync obtained from the EFM signal, and a negative pulse. 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 cycle of 136μs (during normal speed).
C2PO represents the data error status.
XRAOF is generated when the 16K RAM exceeds the ±4F jitter margin.
