UICELL [15:0]:
UICELL[15:0] represents the number of idle/unassigned cells that have been
dropped since the last time the idle/unassigned cell counter was polled. Note
that this counter operates only when idle/unassigned cell filtering is enabled.
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 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). Idle/Unassigned Cells are not accumulated when the RXCP has
declared an out of cell delineation defect state.
