the M13 MUX block (for Interrupt Generation) at the block level, the user still needs to enable the interrupts at the Source
level as well, in order for these interrupts to be enabled.
However, if the user disables the M13 MX block (for Interrupt Generation) at the Block Level, then ALL M13 MUX block-
related interrupts are disabled.
`
0 - Disables all M13 MUX block-related interrupts.
`
1 - Enables all M13 MUX block-related interrupts.
Bits 3 - 2 - Unused
Bit 1 - Transmit DS3 Framer Block Interrupt Enable:
This READ/WRITE bit-field is used to enable or disable the Transmit DS3 Framer block for Interrupt Generation. If the
user enables the Transmit DS3 Framer block (for Interrupt Generation) at the block level, the user still needs to enable
the interrupts at the Source level as well, in order for these interrupts to be enabled.
However, if the user disables the Transmit DS3 Framer block (for Interrupt Generation) at the Block Level, then ALL
Transmit DS3 Framer block-related interrupts are disabled.
`
0 - Disables all Transmit DS3 Framer block-related Interrupts.
`
1 - Enables the Transmit DS3 Framer block for Interrupt Generation (at the Block Level).
Bit 0 - One Second Interrupt Enable:
This READ/WRITE bit-field is used to enable or disable the One-Second Interrupt within the DS3/E3 Framer block. If
the user enables this interrupt, then the DS3/E3 Framer block will generate an interrupt at one second intervals.
0 - Disables the One Second Interrupt
1 - Enables the One Second Interrupt.
Bit 7 - Receive DS3 Framer Bock Interrupt Status:
This READ-ONLY bit-field indicates whether or not the Receive DS3 Framer block is requesting interrupt service.
`
0 - Indicates that the Receive DS3 Framer block is NOT currently requesting interrupt service.
`
1 - Indicates that the Receive DS3 Framer block is currently requesting interrupt service.
Bits 6 - 5 - Unused:
Bit 4 - M13 MUX Block Interrupt Status:
This READ-ONLY bit-field indicates whether or not the M13 MUX block is requesting interrupt service.
`
0 - Indicates that the M13 MUX block is NOT currently requesting interrupt service.
`
1 - Indicates that the M13 MUX block is currently requesting interrupt service.
Bits 3 - 2 - Unused
Bit 1 - Transmit DS3 Framer Block Interrupt Status:
This READ-ONLY bit-field indicates whether or not the Transmit DS3 Framer block is requesting interrupt service.
`
0 - Indicates that the Transmit DS3 Framer block is NOT currently requesting interrupt service.
`
1 - Indicates that the Transmit DS3 Framer block is currently requesting interrupt service.
Bit 0 - One Second Interrupt Status:
