DMO_n

Driver Monitor Output: This bit is set to a “1” to indicate

transmit driver failure is detected. The value of this bit is based

on the current status of DMO for the corresponding channel. If

the DMOIE bit is enabled, any transition on this bit will gener-

ate an Interrupt.

FLS_n

FiFO Limit Status: This bit is set to a “1” to indicate that the jit-

ter attenuator read/write FIFO pointers are within +/- 3 bits. If

the FLSIE bit is enabled, any transition on this bit will generate

an Interrupt.

LCV_n

Line Code Violation: This bit is set to a “1” to indicate that the

receiver of channel n is currently detecting a Line Code Viola-

tion or an excessive number of zeros in the B8ZS or HDB3

modes. If the LCVIE bit is enabled, any transition on this bit will

generate an Interrupt.
