CHCSE[11:0]:

CHCSE[11:0] represents the number of correctable header check sequence

(CHCS) errors that have been detected since the last time the CHCSE error

counter was polled. The counter (and all other counters in the S/UNI-MPH) is

polled by writing to the Global Monitoring register (00CH). Such a write

transfers the internally accumulated count to the CHCSE Error Count

Registers and simultaneously resets the internal counter to begin a new cycle

of error accumulation. The transfer in progress (TIP) bit in register 00CH is

polled to determine when the transfer is complete. The CPPM counters in

each quadrant can also be polled by writing to any address from X60H to

X6FH (where X is a value from 0 to 3). CHCS errors are not accumulated

when the RXCP has declared an out of cell delineation defect state.
