RCELL[15:0]:

RCELL[15:0] represents the aggregate number of cells that have been written

to the receive FIFO since the last time the idle/unassigned cell counter was

polled. Note that this counter represents the number error-free (or error-

corrected), assigned cells that have been received when idle/unassigned cell

filtering and HCS error filtering are enabled. The counter (and all other

counters in the S/UNI-MPH) is polled by writing to the Global Monitoring

the UICELL Cell 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).

Cells are not passed through the RXCP when an out of cell delineation defect

state is declared.
