Notes)
PCMD is a MSB first, two's complement output.
GTOP is used to monitor the frame sync protection status. (High: sync protection window released.)
XUGF is the frame sync obtained from the EFM signal, and is negative pulse. It is the signal before
sync protection.
XPCK is the inverse of the EFM PLL clock. The PLL is designed so that the falling edge and the
EFM signal transition point coincide.
The GFS signal goes high when the frame sync and the insertion timing match.
RFCK is derived from the crystal accuracy, and has a cycle of 136μs.
C2PO represents the data error status.
XROF is generated when the 16K RAM exceeds the ±4F jitter margin.
