M13 MULTIPLEXER/CLEAR CHANNEL DS3 FRAMER IC
REV. P1.0.6
This âRead/Writeâ bit-field permits the user to enable
or disable all âReceive DS3 Framerâ related interrupts
(within the XRT72L13) at the âBlock Levelâ.
Setting this bit-field to â0â disables all âReceive DS3
Framerâ related interrupts within the XRT72L13 M13
device.
Setting this bit-field to â1â enables all âReceive DS3
Framerâ related interrupts (within the XRT72L13 M13
device) at the âBlock Levelâ.
NOTE: Setting this bit-field to â1â does not enable all
âReceive DS3 Framerâ related interrupts. Each of these
interrupts can still be disabled at the âSourceâ Level. How-
ever, setting this bit-field to â0â does disable all âReceive
DS3 Framerâ related interrupt.
Bit 4 - M13 Interrupt Enable
This âRead/Writeâ bit-field permits the user to enable-
or disable all âM13 Multiplexerâ related interrupts
(within the XRT72L13) at the âBlock Level.
Setting this bit-field to â0â disables all âM13 Multiplex-
erâ related interrupts within the XRT72L13 M13 de-
vice.
Setting this bit-field to â1â disables all âM13 Multiplex-
erâ related interrupts (within the XRT72L13 M13 de-
vice) at the âBlock Levelâ.
Bit 1 - Tx DS3 Interrupt Enable
This âRead/Writeâ bit-field permits the user to enable
or disable the âTransmit DS3 Framerâ related inter-
rupts (within the XRT72L13) at the Block Level.
Setting this bit-field to â0â disables all âTransmit DS3
Framerâ related interrupts within the XRT72L13 M13
device.
Setting this bit-field to â1â disables all âTransmit DS3
Framerâ related interrupts (within the XRT72L13 M13
device) at the âBlock Levelâ.
Bit 0 - One Second Interrupt Enable
This âRead/Writeâ bit-field permits the user to enable
or disable the âOne Secondâ Interrupt, within the
XRT72L13. If this interrupt is enabled then the
XRT72L13 will generate interrupts to the Micropro-
cessor/Microcontroller at âone-secondâ intervals.
Setting this bit-field to â0â disables the âOne Secondâ
interrupt. Conversely, setting this bit-field to â1â en-
ables the âOne Secondâ interrupt.

Bit 7 - Rx DS3 Interrupt Status
This âRead-Onlyâ bit-field indicates whether or not a
âReceive DS3 Framerâ related Interrupt has been re-
quested and is awaiting service.
If this bit-field is set to â0â, then there are no âReceive
DS3 Framerâ related interrupts awaiting service.
Conversely, if this bit-field is set to â1â, then there is at
least one âReceive DS3 Framerâ related interrupt,
awaiting service.
Bit 4 - M13 Multiplexer Interrupt Status
This âRead-Onlyâ bit-field indicates whether or not an
âM13 Multiplexerâ related interrupt has been request-
ed and is awaiting service.
If this bit-field is set to â0â, then there are no âM13
Multiplexerâ related interrupts awaiting service. Con-
versely, if this bit-field is set to â1â, then there is at
least one âM13 Multiplexerâ related interrupt, awaiting
service.
Bit 1 - Tx DS3 Interrupt Status
This âRead-Onlyâ bit-field indicates whether or not a
âTransmit DS3 Framerâ related interrupt has been re-
quested and is awaiting service.
