Bits 0 to 7/The host should always write 0x00 to this register when latching the PMON counter.
This register is provided for latching in the 16-bit transmit assigned cell-count value of a port into the common
transmit assigned cell-counter latch register. For reading the transmit assigned cell-count value, software writes
into this register and then reads from transmit-assigned cell-counter MSB and LSB registers. A write into this
register clears the transmit-assigned cell-count value.

Bits 0 to 7/Transmit-Assigned Cell Count (TACC0 to TACC7)
Transmit-assigned cell-count value reflects the number of ATM layer cells transmitted since last latching. For
reading the 16-bit transmit-assigned cell count for a port, software has to write into the transmit PMON-counter
latch-enable register for the port before reading these registers. Reading from these registers without writing into
the latch-enable register returns the old value that was latched and not the current MSB value.
