CMP0
(00H)
Bit Error Rate Compare Word 7 to 0.
CMP7 is the most significant bit and
CMP0 is the least significant bit of a bit
pattern that is compared with the data of
the selected receive circular buffer one.
When individual bit mismatches are
detected the Bit Error Rate Counter
(BERC) is incremented.

7
START0
(0)
Start Receive Circular Buffer Zero. If
one, circular buffer zero will start to
accumulate data when a mismatch is
made between the selected received
data and the data of the code detect
word. If zero, this feature is disabled.
6
START0
(0)
Start Receive Circular Buffer Zero. If
one, circular buffer zero will start to
accumulate data when a positive
match is made between the selected
received data and the data of the
code detect word. If zero, this feature
is disabled.
5
START1
(0)
Start Receive Circular Buffer One. If
one, circular buffer one will start to
accumulate data when a mismatch is
made between the selected received
data and the data of the code detect
word. If zero, this feature is disabled.
4
START1
(0)
Start Receive Circular Buffer One. If
one, circular buffer one will start to
accumulate data when a positive
match is made between the selected
received data and the data of the
code detect word. If zero, this feature
is disabled.
3
STOP0
(0)
Stop Receive Circular Buffer Zero. If
one, circular buffer zero will stop
accumulating data when a mismatch
is made between the selected
received data and the data of the
code detect word. If zero, this feature
is disabled.
2
STOP0
(0)
Stop Receive Circular Buffer Zero. If
one, circular buffer zero will stop
accumulating data when a positive
match is made between the selected
received data and the data of the
code detect word. If zero, this feature
is disabled.

STOP1
(0)
Stop Receive Circular Buffer One. If
one, circular buffer one will stop
accumulating data when a mismatch
is made between the selected
received data and the data of the
code detect word. If zero, this feature
is disabled.
0
STOP1
(0)
Stop Receive Circular Buffer One. If
one, circular buffer one will stop
accumulating data when a positive
match is made between the selected
received data and the data of the
code detect word. If zero, this feature
