DMO
Digital Monitor Output
The digital monitor output is always active regardless if the inter-
rupt generation is disabled. This bit indicates the DMO activity. An
interrupt will not occur unless the DMOIE is set to "1" in the chan-
nel register 0xN04h and GIE is set to "1" in the global register
0x0000h.
0 = No Alarm
1 = Transmit output driver has failures
RO
0
D5
FLS
FIFO Limit Status
The FIFO limit status is always active regardless if the interrupt
generation is disabled. This bit indicates whether the RD/WR
pointers are within 3-Bits. An interrupt will not occur unless the
FLSIE is set to "1" in the channel register 0xN04h and GIE is set to
"1" in the global register 0x0000h.
0 = No Alarm
1 = RD/WR FIFO pointers are within ±3-Bits
RO
0
D4
LCV_OF
Line Code Violation / Counter Overflow
This bit serves a dual purpose. By default, this bit monitors the line
code violation activity. However, if bit 7 in register 0x0005h is set
to a "1", this bit monitors the overflow status of the internal LCV
counter. An interrupt will not occur unless the LCV_OFIE is set to
"1" in the channel register 0xN04h and GIE is set to "1" in the glo-
bal register 0x0000h.
0 = No Alarm
1 = A line code violation, bipolar violation, or excessive zeros has
occurred
RO

D3
Reserved
This Bit is Reserved
RO

D2
AISD
Alarm Indication Signal Detection
The alarm indication signal detection is always active regardless if
the interrupt generation is disabled. This bit indicates the AIS
activity. An interrupt will not occur unless the AISIE is set to "1" in
the channel register 0xN04h and GIE is set to "1" in the global reg-
ister 0x0000h.
0 = No Alarm
1 = An all ones signal is detected
