Bit 3: Performance Monitoring Update Status (PMS) – This bit indicates the status of the receive performance
monitoring register (counters) update. This bit will transition from low to high when the update is completed. PMS
will be forced low when the LPMU bit (PMUM = 0) or the global or port PMU bit (PMUM=1) goes low.
Bit 1: Bit Error Count (BEC) – When 0, the bit error count is zero. When 1, the bit error count is one or more. This
bit is cleared when the user updates the BERT counters via the PMU bit (BERT.CR).
Bit 0: Out Of Synchronization (OOS) – When 0, the receive pattern generator is synchronized to the incoming
pattern. When 1, the receive pattern generator is not synchronized to the incoming pattern.

Bit 3: Performance Monitoring Update Status Latched (PMSL) – This bit is set when the PMS bit transitions
from 0 to 1.
Bit 2: Bit Error Latched (BEL) – This bit is set when a bit error is detected.
Bit 1: Bit Error Count Latched (BECL) – This bit is set when the BEC bit transitions from 0 to 1.
Bit 0: Out Of Synchronization Latched (OOSL) – This bit is set when the OOS bit changes state.
