Error Counter Update Select. See Section
0 = update error counters once a second
1 = update error counters every 62.5ms (500 frames)
VCR Function Select. See Section
0 = count BiPolar Violations (BPVs)
1 = count Code Violations (CVs)
Automatic Transmit AIS Generation.
0 = disabled
1 = enabled
Automatic Remote Alarm Generation.
0 = disabled
1 = enabled
RSER Control.
0 = allow RSER to output data as received under all conditions
1 = force RSER to one under loss of frame alignment conditions
Loss of Transmit Clock Mux Control. Determines whether the
transmit-side formatter should switch to the ever-present RCLKO if the
TCLK should fail to transition (see
0 = do not switch to RCLKO if TCLK stops
1 = switch to RCLKO if TCLK stops
Receive Force Freeze. Freezes receive-side signaling at RSIG (and TS16
in RSER if CCR3.3 = 1); will override Receive Freeze Enable (RFE).
See Section
0 = do not force a freeze event
1 = force a freeze event
Receive Freeze Enable. See Section
0 = no freezing of receive signaling data will occur
1 = allow freezing of receive signaling data at RSIG (and TS16 in RSER
if CCR3.3 = 1).
