This Read-Only register, along with the Frame Parity
Errors - One-Second Accumulator Register - LSB
(Address = 0x71) contains a 16-bit representation of
the number of Frame Parity Errors that have been de-
tected by the Receive DS3/E3 Framer block, within
the last One-Second sampling period. This register
contains the MSB (or Upper-Byte) value of this 16 bit
expression.

This Read-Only register, along with the Frame CP-Bit
Error - One-Second Accumulator Register - LSB (Ad-
dress = 0x73) contains a 16-bit representation of the
number of CP Bit Errors tjhat have been detected by
the Receive DS3/E3 Framer block, within the last
one-second sampling period. This register contains
the MSB (or Upper Byte) value of this 16-bit expres-
sion.
