Bit #
Name
Default
Bits 0 to 3/Receive Level Bits (RL0 to RL3). Real-time bits
Bit 4/Transmit Open-Circuit Detect (TOCD). A real-time bit that is set when the device detects that the TTIP
and TRING outputs are open-circuited.
Bit 5/Transmit Current-Limit Exceeded (TCLE). A real-time bit that is set when the 50mA (RMS) current
limiter is activated, whether the current limiter is enabled or not.
Bit 6/BOC Detected (BD). A real-time bit that is set high when the BOC detector is presently seeing a valid
sequence and set low when no BOC is currently being detected.
Bit 7/BERT Real-Time Synchronization Status (BSYNC). Real-time status of the synchronizer (this bit is not
latched). This bit is set when the incoming pattern matches for 32 consecutive bit positions. It is cleared when six
or more bits out of 64 are received in error. Refer to BSYNC in the BERT status register, SR9, for an interrupt-
generating version of this signal.
