TCELL[15:0]:
TCELL[15:0] represents the aggregate number of assigned cells that have
been transmitted since the last time the transmit cell 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 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).
