Bit

Name

Functional Description

7START0

(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.

6START0

(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.

5START1

(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.

4START1

(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.

3STOP0

(0)

Stop Receive Circular Buffer Zero. If

one, circular buffer zero will stop

accumulating data when a mismatch

made

between

the

selected

received data and the data of the

code detect word. If zero, this feature

is disabled.

2STOP0

(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.

1STOP1

(0)

Stop Receive Circular Buffer One. If

one, circular buffer one will stop

accumulating data when a mismatch

made

between

the

selected

received data and the data of the

code detect word. If zero, this feature

is disabled.

0STOP1

(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

is disabled.

Data

loaded into the E-bit Error counter

when this bit is changed from low to

high.

LDBPV

(0)

loaded into the Bipolar Violation

counter when this bit is changed from

low to high.

LDEF

(0)

Errored

Frame

Alignment

Load

Word. Data is loaded into the Errored

Frame Alignment counter when this

bit is changed from low to high.

1LDRC

(0)

RAI and Continuous CRC Error Load

Word. Data is loaded into the RAI

and Continuous CRC Error counter

when this bit is changed from low to

high.

LDBER

(0)

Bit Error Rate Load Word. Data is

loaded into the eight bit BER counter

when this bit is changed from low to

high.
