These registers allow path FEBEs to be accumulated.

PFE[15:0]:

PFE[15:0] represent the number of path FEBE errors (G1) 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 FEBE 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).
