Terminal
Synchronization
When unmasked this interrupt
bit
change of state of terminal
frame synchronization condition
exists. Reading this register
clears this bit.
Multiframe
Interrupt. When unmasked this
interrupt bit goes high whenever
a change of state of multiframe
synchronization
exists. Reading this register
clears this bit.
CRC-4
Interrupt. When unmasked this
interrupt bit goes high whenever
change of state of CRC-4
synchronization
exists. Reading this register
clears this bit.
Alarm
Interrupt. When unmasked this
interrupt bit goes high whenever
a change of state of received all
ones condition exists. Reading
this register clears this bit.
