This register contains the least significant bits of a 16 bit count of the number of ATM
layer cells transmitted over the Transmit links within the group. The register is read
only. Status clears upon read.

Transmit Group Cell Count: This field contains the least significant bits of a
16-bit count of the number of ATM layer cells transmitted over the Transmit
links within the group. A write operation with data = 0x01 to the first address
(0x440 for Group #1, 0x442 for Group #2, etc.) transfers the state of all 16
bits of the counter to registers that are accessible to the microprocessor bus
and clears the state of the counter, The first address should be read first. The
second address (0x441 for Group #1, 0x443 for Group #2, etc.) is read next.
A write operation with data = 0x00 to the first address of each group returns
back to the raw counters.
