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