Performance Monitor - Transmit Slip Counter (8-bit Counter)
These Reset-Upon-Read bit fields reflect the cumulative number of
instances that Transmit Slip events have been detected by the T1
Framer since the last read of this register.
N
OTE
:
A slip event is defined as a replication or deletion of a T1
frame by the transmit slip buffer.

Performance Monitor - T1 Excessive Zero Violation 16-Bit
Counter - Upper Byte:
These RESET-upon-READ bits, along with that within the “PMON
T1 Excessive Zero Violation Counter Register LSB” combine to
reflect the cumulative number of instances that the ReceiveT1
Excessive Zero Violation 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 T1 Excessive Zero Violation counter.
N
OTE
:
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.

Performance Monitor - T1 Excessive Zero Violation 16-Bit
Counter - Lower Byte:
These RESET-upon-READ bits, along with that within the “PMON
T1 Excessive Zero Violation Counter Register MSB” combine to
reflect the cumulative number of instances that the ReceiveT1
Excessive Zero Violation 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 T1 Excessive Zero Violation counter.
