Function
Multi Function Port
Depending on programming of bits
LIM4.PC(2:0) this multifunction port
provides different status information of the
device as shown in this table below.
MFP1 corresponds to channel 1, MFP4 to
channel 4.
Loss-of-Signal Indication
LIM4.PC(2:0) = 000
Active high, if a loss-of-signal alarm is
detected. This signal corresponds directly
to bit LSR0.LOS.
Analog Loss-of-Signal Indication
LIM4.PC(2:0) = 001
Active high, if the input level at RL1/2 drops
below the programmed receive input
threshold which is defined by register
LIM2.RIL(2:0).
PRBS Synchronization Status
LIM4.PC(2:0) = 010
Active high if the Pseudo-Random Bit
Sequence (PRBS) synchronization is
achieved. This signal corresponds directly
to bit LSR0.PRBSS.
Bipolar Violation Indication
LIM4.PC(2:0) = 011
Active high if a bipolar violation is detected.
This signal corresponds directly to the
increment signal of the code violation error
counter.
