TX_ABT[15:0]:
The TX_ ABT[15:0] bits indicate the number aborted packets transmitted to the TCFP egress
stream during the last accumulation interval. These counters are only valid when processing
packets.
A write to any one of the TCFP Transmit Byte Counter registers loads the registers with the
current counter value and resets the internal 16 bit counter to 1 or 0. The counter reset value
is dependent on if there was a count event during the transfer of the count to the Transmit
Byte Counter registers. The counter should be polled regularly to avoid saturating.
To allow for synchronization update with all other blocks, register 0000H can be written to
initiate a global performance counter update.
