DESCRIPTION
R/W DS3/E3 LIU/JA Block Interrupt Enable:
This READ/WRITE bit permit the user to either enable or disable
the DS3/E3 LIU/JA Block for interrupt generation. If the user
writes a "0" to this register bit and disables the "DS3/E3 LIU/JA
Block" (for interrupt generation), then all "DS3/E3 LIU/JA Block"
interrupts will be disabled for interrupt generation. If the user
writes a "1" to this register bit, he/she will still need to enable the
individual "DS3/E3 LIU/JA Block" interrupt(s) at the "Source
Level" in order to enable that particular interrupt.
0 - Disable all "DS3/E3 LIU/JA Block" interrupts within the
device.
1 - Enables the "DS3/E3 LIU/JA Block" at the "Block-Level".
R/W DS3/E3 Framer Block Interrupt Enable:
This READ/WRITE bit permits the user to either enable or dis-
able the DS3/E3 Framer Block for interrupt generation. If the
user writes a "0" to this register bit and disables the "DS3/E3
Framer Block" (for interrupt generation), then all "DS3/E3 Framer
Block" interrupts will be disabled for interrupt generation. If the
user writes a "1" to this register bit, he/she will still need to
enable the individual "DS3/E3 Framer Block" interrupt(s) at the
"Source Level" in order to enable that particular interrupt.
0 - Disable all "DS3/E3 Framer Block" interrupts within the
device.
1 - Enables the "DS3/E3 Framer Block" at the "Block-Level".
