CRC-6 Error Counter Bits Fifteen to Eight. These are the most significant
eight bits of the CRC-6 error counter.
Terminal Frame Synchronization Interrupt. When unmasked this interrupt
bit goes high whenever a change of state of terminal frame synchronization
condition exists. Reading this register clears this bit.
Multiframe Synchronization Interrupt. When unmasked this interrupt bit
goes high whenever a change of state of multiframe synchronization
condition exists. Reading this register clears this bit.
Unused.
Alarm Indication Signal 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.
Loss of Signal Interrupt. When unmasked this interrupt bit goes high
whenever a change of state of loss of signal (either analog - signal 40 dB
below nominal or digital - 192 consecutive 0’s received) condition exists.
Reading this register clears this bit.
Severely Errored Frame Interrupt. When unmasked this interrupt bit goes
high whenever a sequence of 2 framing errors out of 6 occurs. Reading this
register clears this bit.
Transmit SLIP Interrupt. When unmasked this interrupt goes high
whenever a controlled frame slip occurs in the transmit elastic buffer.
Reading this register clears this bit.
Receive SLIP Interrupt. When unmasked this interrupt bit goes high
whenever a controlled frame slip occurs in the receive elastic buffer. Reading
this register clears this bit.
CRC-6 Error Counter Bits Seven to Zero. These are the least significant
eight bits of the CRC-6 error counter.
