BVD7
BVCR.7
MSB of bipolar count.
BDV0
BVCR.0
LSB of bipolar count.
This 8-bit binary up counter saturates at 255 and will generate an interrupt for each occurrence of a
bipolar violation once saturated (RIMR.7=1). Presetting this register allows the user to establish specific
count interrupt thresholds. The counter will count “up” to saturation from the preset valued and may be
read at any time. Counter increments occur at all times and are not disabled by resync. If B8ZS is enabled
(CCR.2=1) bipolar violations are not counted for B8ZS code words.

ECR.0
LSB of extended superframe error count.
These separate 4-bit binary up counters saturate at a count of 15 and will generate an interrupt for each
occurrence of an OOF event or an ESF error event after saturation (RIMR.6=1). Presetting these counters
allows the user to establish specific count interrupt thresholds. The counters will count “up” to saturation
from the preset value and may be read at any time. These counters share the same register address and
must be written to or read from simultaneously.
The OOF counter records out-of-frame events in both 193S and 193E. The ESF error counter records
errored superframes in 193E. In 193S, the ESF counter records individual FT and FS errors when
RCR.3=1; FT errors only when RCR.3=0. ECR counter increments are disabled when resync is in
progress (RLOS high).
ALARM OUTPUTS
The transceiver also provides direct alarm outputs for applications when additional decoding and
demuxing are required to supplement the onboard alarm logic.
RLOS OUTPUT
The receive loss of sync output indicates the status of the receiver synchronizer circuitry; when high, an
off-line resynchronization is in progress and a high-low transition indicates resync is complete. The
RLOS bit (RSR.0) is a “latched” version of the RLOS output. If the auto-resync mode is selected
(RCR.1=0), RLOS is a real time indication of a carrier loss or OOF event occurrence.
