Pulse
Interrupt
unmasked
triggered whenever a sequence
of excessive consecutive zeros
is received on the line, or the
incoming pulse density is less
than N ones in a time frame of
8(N+1) where N = 1 to 23. If 1 -
unmasked, 0 - masked.

Functional Description
Framing Bit Error Counter
Overflow Interrupt Mask.
When unmasked an interrupt
is initiated whenever the
framing bit error counter
changes from FFH to 00H. If
1 - unmasked, 0 - masked.
CRC-6
Overflow Interrupt Mask.
When unmasked an interrupt
is initiated whenever the
CRC-6
changes from FFH to 00H. If
1 - unmasked, 0 - masked.
