Bit Oriented Message Interrupt. When unmasked this interrupt bit goes
high whenever a pattern 111111110xxxxxx0 has been received on the FDL
that is different from the last message. The new message must persist for 8
out the last 10 message positions to be accepted as a valid new message.
Reading this register clears this bit.
Signaling Interrupt. When unmasked this interrupt bit goes high whenever
a change of state (optionally debounced - see DBEn in the Data Link,
Signaling Control Word page 1 address 12H) is detected in the signaling
bits (AB or ABCD) pattern. Reading this register clears this bit.
Table 70 - Overflow Reporting Latch
Framing Bit Error Counter Overflow Latch. This bit is set when the
framing bit counter overflows. It is cleared after being read.
CRC-6 Error Counter Overflow Latch. This bit is set when the crc error
counter overflows. It is cleared after being read.
Out Of Frame Counter Overflow Latch. This bit is set when the out of
frame counter overflows. It is cleared after being read.
Change of Frame Alignment Counter Overflow Latch. This bit is set
when the change of frame alignment counter overflows. It is cleared after
being read.
Bipolar Violation Counter Overflow Latch. This bit is set when the
bipolar violation counter overflows. It is cleared after being read.
Psuedo Random Bit Sequence Error Counter Overflow Latch. This bit
is set when the PRBS error counter overflows. It is cleared after being
read.
Psuedo Random Bit Sequence Multiframe Counter Overflow Latch.
This bit is set when the multiframe counter attached to the PRBS error
counter overflows. It is cleared after being read
Multiframes Out Of Sync Overflow Latch. This bit is set when the
multiframes out of sync counter overflows. It is cleared after being read.
