Bits 5-3: Transmit Error Insertion Rate (TEIR[2:0]). These three bits indicate the rate at which errors are inserted
in the output data stream. One out of every 10
n bits is inverted. TEIR[2:0] is the value n. A TEIR[2:0] value of 0
disables error insertion at a specific rate. A TEIR[2:0] value of 1 result in every 10
th bit being inverted. A TEIR[2:0]
value of 2 result in every 100
th bit being inverted. Error insertion starts when this register is written to with a
TEIR[2:0] value that is non-zero. If this register is written to during the middle of an error insertion process, insertion
at the new error rate is started after the next error is inserted.
Bit 2: Bit Error Insertion Enable (BEI). When 0, single bit error insertion is disabled. When 1, single bit error
insertion is enabled.
Bit 1: Transmit Single Error Insert (TSEI). This bit causes a bit error to be inserted in the transmit data stream if
single bit error insertion is enabled (BEI=1). A 0-to-1 transition causes a single bit error to be inserted. For a
second bit error to be inserted, this bit must be set to 0, and back to 1. Note: If this bit transitions more than once
between error insertion opportunities, only one error is inserted.

Bit 3: Performance Monitoring Update Status (PMS). This bit indicates the status of the receive performance
monitoring register (counters) update. This bit transitions from low to high when the update is completed. PMS is
asynchronously forced low when the
BCR.LPMU bit goes low
(BCR.PMUM = 0) or when the
GCR2.BRPMU bit
Bit 1: Bit Error Count (BEC). When 0, the bit error count
(RBECR registers) is zero. When 1, the bit error count is
one or more.
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.
