FERIM
Frame Error Interrupt Mask
. When
unmasked (FERI = 1), an interrupt is
initiated when an error in the frame
alignment signal occurs. If 1 -
unmasked, 0 - masked.
6
CRCIM
CRC-4 Error Interrupt Mask
. When
unmasked an interrupt is initiated
when a local CRC-4 error occurs. 1 -
unmasked, 0 - masked. If 1 -
unmasked, 0 - masked.

EBIM
Receive E-bit Interrupt Mask
. When
unmasked an interrupt is initiated
when a receive E-bit indicates a
remote CRC-4 error. 1 - unmasked, 0
- masked. If 1 - unmasked, 0 -
masked.

AIS16IM
Channel 16 Alarm Indication Signal
Interrupt Mask
. When unmasked
(AIS16I = 1), a received AIS16 will
initiate an interrupt. If 1 - unmasked, 0
- masked.
3
BPVIM
Bipolar Violation Interrupt Mask
.
When unmasked an interrupt is
initiated when a bipolar violation error
occurs. 1 - unmasked, 0 - masked.

AUXPIM
Auxiliary Pattern Interrupt Mask.
When unmasked (AUXPI = 1), an
interrupt is initiated when the AUXP
