M13 MULTIPLEXER/CLEAR CHANNEL DS3 FRAMER IC XRT72L13
REV. 1.0.6
This âRead/Writeâ bit-field permits the user to enable
or disable the âDS2 Far-End Receive Failureâ Inter-
rupt.
Setting this bit-field to â1â enables this interrupt. Con-
versely, setting this bit-field to â0â disables this inter-
rupt.
Bit 2 - DS2 RED Alarm Interrupt Enable
This âRead/Writeâ bit-field permits the user to enable
or disable the âDS2 RED Alarmâ Interrupt.
Setting this bit-field to â1â enables this interrupt. Con-
versely, setting this bit-field to â0â disables this inter-
rupt.
Bit 1 - DS2 AIS Interrupt Enable
This âRead/Writeâ bit-field permits the user to enable
or disable the âDS2 AISâ Interrupt.
Setting this bit-field to â1â enables this interrupt. Con-
versely, setting this bit-field to â0â disables this inter-
rupt.
Bit 0 - DS2 RESV Interrupt Enable.
To be provided in the next update.

Bit 5 - Change in DS2 COFA (Change of Framing
Alignment) Interrupt Status
This âReset-upon-Readâ bit-field indicates whether or
not a change in the âDS2 COFA Stateâ has occurred
since the last read of this register.
This bit-field will be set to â1â if a change in the DS2
COFA State has occurred since the last read of this
register. Conversely, this bit-field will be set to â0â if a
change in the DS2 COFA State has NOT occurred
since the last read of this register.
Bit 4 - Change in DS2 OOF (Out-of-Frame) Inter-
rupt Status
This âReset-upon-Readâ bit-field indicates whether or
not a change in the âDS2 Out-of-Frame Stateâ has
occurred since the last read of this register.
This bit-field will be set to â1â if a change in the DS2
OOF State has occurred since the last read of this
register. Conversely, this bit-field will be set to â0â if a
change in the DS2 OOF State has NOT occurred
since the last read of this register.
Bit 3 - Change in DS2 FERF (Far-End Receive Fail-
ure) Interrupt Status
This âReset-upon-Readâ bit-field indicates whether or
not a change in the âDS2 FERF Stateâ has occurred
since the last read of this register.
This bit-field will be set to â1â if a change in the DS2
FERF State has occurred since the last read of this
register. Conversely, this bit-field will be set to â0â if a
change in the DS2 FERF State has NOT occurred
since the last read of this register.
Bit 2 - Change in DS2 RED Alarm Interrupt Status
This âReset-upon-Readâ bit-field indicates whether or
not a change in the âDS2 RED Alarm Stateâ has oc-
curred since the last read of this register.
This bit-field will be set to â1â if a change in the DS2
RED Alarm State has occurred since the last read of
this register. Conversely, this bit-field will be set to â0â
if a change in the DS2 RED Alarm State has NOT oc-
curred since the last read of this register.
Bit 1 - Change in DS2 AIS Interrupt Status
This âReset-upon-Readâ bit-field indicates whether or
not a change in the âDS2 AIS Stateâ has occurred
since the last read of this register.
This bit-field will be set to â1â if a change in the DS2
AIS State has occurred since the last read of this reg-
ister. Conversely, this bit-field will be set to â0â if a
change in the DS2 AIS State has NOT occurred since
the last read of this register.
Bit 0 - Change in DS2 RESV Interrupt Status
