Description
Loss of signal alarm for channel x. Read only register.
When the loss of signal is detected, LOSx is set High.
Loss of TCLK alarm for channel x. Read only register.
When the loss of TCLKx is detected, LOTCx is set High.
Driver Performance Monitor alarm for channel x. Read only register.
When 320 bits of consecutive space is detected in channel x, DPMx is set
high.
Driver Failure Monitor alarm for channel x. Read only register.
When DPM or short circuit is detected in channel x , DFMx is set high.
Analog loss of signal alarm for channel x. Read only register.
When the analog loss of signal is detected, ALOSx is set High.
Loss of MCLK alarm. Read only register.
When the loss of MCLK is detected, LOMC is set High.

MLOMC
Description
Mask loss of signal alarm for channel x (LOSx).
MLOSx is active-high and prevents LOSx from setting INT output “high”.
LOSx register can be read regardless of the MLOSx status.
Initial value is “high”.
Mask loss of TCLK alarm for channel x (LOTCx).
MLOTCx is active high and prevents LOTCx from setting INT output
“high”. LOTCx register can be read regardless of the MLOTCx status.
Initial value is “high”.
Mask DPM alarm for channel x (DPMx).
MDPMx is active high
Initial value is “high”.
Mask DFM alarm for channel x (DFMx).
MDFMx is active high
Initial value is “high”.
MSKx is active-high and prevents LOSx, LOTCx, DFMx and DPMx in
channel x from setting INT output “high”. Initial value is “high”.
Mask analog loss of signal alarm for channel x (ALOSx).
MALOSx is active-high and prevents ALOSx from setting INT output
“high”. ALOSx register can be read regardless of the MALOSx status.
Initial value is “high”.
Mask loss of MCLK alarm (LOMC).
MLOMC is active high and prevents LOMC from setting INT output “high”.
LOMC register can be read regardless of the MLOMC status.
Initial value is “high”.
