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).
