REV. 1.0.6
Setting this bit-field to “0” permits data to be output
(via the RxDS1Data22 output pin, as demultiplexed
via the inbound DS2 and DS3 data streams.
Bit 5 - insert AIS Rx DS1 Channel 21
This “Read/Write” bit-field permits the user to config-
ure the contents of the “inbound” DS1 Channel 21 to
be overwritten with an “All Ones” pattern.
Setting this bit-field to “0” permits data to be output
(via the RxDS1Data21 output pin), as demultiplexed
via the inbound DS2 and DS3 data streams.
Bit 4 - Insert AIS Rx DS1 Channel 20
This “Read/Write” bit-field permits the user to config-
ure the contents of the “inbound” DS1 Channel 20 to
be overwritten with an “All Ones” pattern.
Setting this bit-field to “0” permits data to be output
(via the RxDS1Data20 output pin), as demultiplexed
via the inbound DS2 and DS3 data streams.
Bit 3 - Insert AIS Tx DS1 Channel 23
This “Read/Write” bit-field permits the user to config-
ure the contents of the “outbound” DS1 Channel 23 to
be overwritten with an “All Ones” pattern.
Setting this bit-field to “0” permits the contents of DS1
Channel 23 to be transmitted as received (via the
TxDS1Data23 input pin).
Setting this bit-field to “1” configures the XRT72L13
M13 device to overwrite this data with an AIS (all
ones pattern).
Bit 2 - Insert AIS Tx DS1 Channel 22
This “Read/Write” bit-field permits the user to config-
ure the contents of the “outbound” DS1 Channel 22 to
be overwritten with an “All Ones” pattern.
Setting this bit-field to “0” permits the contents of DS1
Channel 22 to be transmitted as received (via the
TxDS1Data22 input pin).
Setting this bit-field to “1” configures the XRT72L13
M13 device to overwrite this data with an AIS (all
ones pattern).
Bit 1 - Insert AIS Tx DS1 Channel 21
This “Read/Write” bit-field permits the user to config-
ure the contents of the “outbound” DS1 Channel 21 to
be overwritten with an “All Ones” pattern.
Setting this bit-field to “0” permits the contents of DS1
Channel 21 to be transmitted as received (via the
TxDS1Data21 input pin).
Setting this bit-field to “1” configures the XRT72L13
M13 device to overwrite this data with an AIS (all
ones pattern).
Bit 0 - Insert AIS Tx DS1 Channel 20
This “Read/Write” bit-field permits the user to config-
ure the contents of the “outbound” DS1 Channel 20 to
be overwritten with an “All Ones” pattern.
Setting this bit-field to “0” permits the contents of DS1
Channel 20 to be transmitted as received (via the
TxDS1Data20 input pin).
Setting this bit-field to “1” configures the XRT72L13
M13 device to overwrite this data with an AIS (all
ones pattern).
