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.
unmasked an interrupt is initiated
when a local CRC-4 error occurs. 1 -
unmasked, 0 - masked. If 1 -
unmasked, 0 - masked.
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.
Interrupt Mask. When unmasked
(AIS16I = 1), a received AIS16 will
initiate an interrupt. If 1 - unmasked, 0
- masked.
Bipolar Violation Interrupt Mask.
When unmasked an interrupt is
initiated when a bipolar violation error
occurs. 1 - unmasked, 0 - masked.
Remote Signaling Multiframe
Alarm Interrupt Mask. When
unmasked (YI=1), an interrupt is
initiated whenever a change of
state

received. If 1 - unmasked, 0 -
masked.
