This "Read-Only" register, along with the "LCV - One
Second Accumulator Register - MSB" (Address =
0x6E) contains a 16-bit representation of the number
of "LCV (Line Code Violation) Events that have been
detected by the Receive DS3 Framer block, within the
last one second sampling period. This register con-
tains the LSB (or Lower-Byte) value of this 16 bit ex-
pression.

(Address = 0x71) contains a 16-bit representation of
the number of "P-bit” Errors that have been detected
by the Receive DS3 Framer block, within the last one
second sampling period. This register contains the
MSB (or Upper-Byte) value of this 16 bit expression.
