35、(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 s

36、ignal goes high when the frame sync and the insertion timing match. RFCK is derived from the crystal accuracy, and has a cycle of 136s. C2PO reqresents the data error status. XROF is generated when the 16K RAM exceeds the 4F jitter margin. Monitor Pin Output Combinations Command bit 00XUGFXPCKGFSC2P
