TCELL[23:0]:
The TCELL[23:0] bits indicate the number of cells inserted into the
transmission stream during the last accumulation interval. Stuff cells inserted
into the transmission stream for rate decoupling are not counted.
A write to any one of the Transmit Cell Counter registers for a particular serial
link or a write to the Load Performance Meters (0x000) register loads the
registers with the current counter value and resets the internal 24 bit counter.
The counter should be polled at least every 30 seconds to avoid saturating.
The contents of these registers become valid within 300 ns after a transfer is
triggered by a write to any of the link-associated Transmit Cell Count
Registers or to the Load Performance Meters (0x000) register, and remain
valid until another transfer is triggered.
The count saturates at all ones.
