Default
Note: All bits in this register are latched and can create interrupts.
Bit 6: BERT Bit-Error-Detected Event (BBED). A latched bit that is set when a bit error is detected. The receive
BERT must be in synchronization for it to detect bit errors.
Bit 5: BERT Bit Counter Overflow Event (BBCO). A latched bit that is set when the 32-bit BERT bit counter
(BBC) overflows.
Bit 4: BERT Error Counter Overflow Event (BECO). A latched bit that is set when the 24-bit BERT error counter
(BEC) overflows.
Bit 3: BERT Receive All-Ones Condition (BRA1). A latched bit that is set when 32 consecutive ones are
received.
Bit 2: BERT Receive All-Zeros Condition (BRA0). A latched bit that is set when 32 consecutive zeros are
received.
Bit 1: BERT Receive Loss of Synchronization Condition (BRLOS). A latched bit that is set whenever the
receive BERT begins searching for a pattern.
Bit 0: BERT in Synchronization Condition (BSYNC). Will be set when the incoming pattern matches for 32
consecutive bit positions.
