Change of Transmit DMO (Drive Monitor Output) Condition Inter-
rupt Enable:
This bit permits the user to either enable or disable the “Change of
Transmit DMO Condition” Interrupt. If the user enables this interrupt,
then the XRT86VL34 device will generate an interrupt any time when
either one of the following events occur.
1. Whenever the Transmit Section toggles the DMO Status bit (Bit 6
or Register 0x0Fn5) to “1”.
2. Whenever the Transmit Section toggles the DMO Status bit (Bit 6
or Register 0x0Fn5) to “0”.
0 – Disables the “Change in the DMO Condition” Interrupt.
1 – Enables the “Change in the DMO Condition” Interrupt.

FIFO Limit Status Interrupt Enable:
This bit permits the user to either enable or disable the “FIFO Limit Sta-
tus” Interrupt. If the user enables this interrupt, then the XRT86VL34
device will generate an interrupt when the jitter attenuator Read/Write
FIFO pointers are within +/- 3 bits.
0 = Disables the “FIFO Limit Status” Interrupt
1 = Enables the “FIFO Limit Status” Interrupt

LCVIE_n
R/W
0
Line Code Violation Interrupt Enable:
This bit permits the user to either enable or disable the “Line Code Viola-
tion” Interrupt. If the user enables this interrupt, then the XRT86VL34
device will generate an interrupt when a LCV error or an excessive zero
condition is detected.
0 = Disables the “Line Code Violation” Interrupt
1 = Enables the “Line Code Violation” Interrupt

0
Change in Network Loop-Code Detection Interrupt Enable:
This bit permits the user to either enable or disable the “Change in Net-
work Loop-Code Detection” Interrupt. If the user enables this interrupt,
then the XRT86VL34 device will generate an interrupt any time when
either one of the following events occur.
1. Whenever the Receive Section (within XRT86VL34) detects the
Network Loop-Code (Loop-Up or Loop-Down depending on which
Loop-Code the Receive LIU is configured to detect).
2. Whenever the Receive Section (within XRT86VL34) no longer
detects
the
Network
Loop-Code
(Loop-Up
or
Loop-Down
depending on which Loop-Code the Receive LIU is configured to
detect).
0 – Disables the “Change in Network Loop-Code Detection” Interrupt.
1 – Enables the “Change in Network Loop-Code Detection” Interrupt.
