PBE[15:0]:
PBE[15:0] represent the number of B3 errors (individual or block) that have
been detected since the last time the error count was polled. The error count
is polled by writing to either of the RPOP Path BIP-8 Register addresses or to
either of the RPOP Path FEBE Register addresses. Such a write transfers
the internally accumulated error count to the Path BIP-8 registers within a
maximum of 7 µs and simultaneously resets the internal counter to begin a
new cycle of error accumulation. This transfer and reset is carried out in a
manner that ensures that coincident events are not lost.
The count can also be polled by writing to the S/UNI-QUAD Channel Reset
and Monitoring Update register (0x05).
