LFE[19:0]

Bits LFE[19:0] represent the number of line FEBE errors (Z2) that have been

detected since the last time the error count was polled. The error count is polled

by writing to any of the RLOP Line BIP Register or Line FEBE Register

addresses. Such a write transfers the internally accumulated error count to the

Line FEBE Registers within approximately 7 µs and simultaneously resets the

internal counter to begin a new cycle of error accumulation.

The error count can also be polled by writing to the LASAR-155 Master

Reset / Load Meters register. Writing to the register loads all the error counter

registers in the SAR PMON, RSOP, RLOP, RPOP, RACP and TACP blocks.
