RMAXL[15:0]:
When POS mode is selected, the RMAXL[15:0] bits indicate the number of maximum length
packet errors received during the last accumulation interval. This counter is held at value 0
when ATM mode is selected.
A write to any one of the RCFP performance monitor registers loads the registers with the
current counter value and resets the internal 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 Receive
Maximum Length Packet 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.
