Receive E-bit Counter Overflow Interrupt. When unmasked an interrupt
is initiated when the E-bit error counter overflows. 1 - unmasked, 0 -
masked. Interrupt vector = 00010000.
CRC-4 Error Counter Overflow Interrupt. When unmasked an interrupt is
initiated when the CRC-4 error counter overflows. 1 - unmasked, 0 -
masked. Interrupt vector = 00010000.
CRC-4 Alignment Interrupt. When unmasked an interrupt is initiated when
the CALN status bit of page 03H, address 12H changes state. 1 -
unmasked, 0 - masked. Interrupt vector = 00001000.
Frame Alignment Signal Error Counter Overflow Interrupt. When
unmasked an interrupt is initiated when the frame alignment signal error
counter overflows. 1 - unmasked, 0 - masked. Interrupt vector = 00010000.
Jitter Attenuation Interrupt. When unmasked, an interrupt will be initiated
when the jitter attenuator FIFO comes within four bytes of an overflow or
underflow condition. 1 - unmasked, 0 - masked. Interrupt vector =
00000100.
Bit Error Counter Overflow Interrupt. When unmasked (BERO = 1), an
interrupt is initiated when the bit error counter overflows. Interrupt vector =
00010000.
Auxiliary Pattern Interrupt. When unmasked (AUXPI = 1), an interrupt is
initiated when the AUXP status bit of page 03H, address 15H goes high.
Interrupt vector = 01000000.
Receive CRC-4 Multiframe Counter Overflow Interrupt. When unmasked
(CMFO = 1), an interrupt is initiated when the CRC-4 multiframe counter
overflows. Interrupt vector = 00010000.
