RFAEC[15]

RUR

Performance Monitor “Receive Framing Alignment Error 16-Bit

counter” - Upper Byte:

These RESET-upon-READ bits, along with that within the “PMON

Receive Framing Alignment Error Counter Register LSB” combine

to reflect the cumulative number of instances that the Receive

Framing Alignment errors has been detected by the Receive T1

Framer block since the last read of this register.

This register contains the Most Significant byte of this 16-bit of the

Receive Framing Alignment Error counter.

NOTE: For all 16-bit wide PMON registers, user must read the MSB

counter first before reading the LSB counter in order to read

the accurate PMON counts. To clear PMON count, user

must read the MSB counter first before reading the LSB

counter in order to clear the PMON count.

RFAEC[7]

RUR

Performance Monitor “Receive Framing Alignment Error 16-Bit

Counter” - Lower Byte:

These RESET-upon-READ bits, along with that within the “PMON

Receive Framing Alignment Error Counter Register MSB” combine

to reflect the cumulative number of instances that the Receive

Framing Alignment errors has been detected by the Receive T1

Framer block since the last read of this register.

This register contains the Least Significant byte of this 16-bit of the

Receive Framing Alignment Error counter.

NOTE: For all 16-bit wide PMON registers, user must read the MSB

counter first before reading the LSB counter in order to read

the accurate PMON counts. To clear PMON count, user

must read the MSB counter first before reading the LSB

counter in order to clear the PMON count.
