Default

All bits in this register are latched and can create interrupts.

Bit 0 / Receive Loss-of-Frame Condition Detect (RLOFD).

Rising edge detect of RLOF. Set when the DS26401

has lost synchronized to the received data stream.

Bit 1 / Receive Loss-of-Signal Condition Detect (RLOSD).

Rising edge detect of RLOS. Set when 192

consecutive zeros have been detected at RPOS and RNEG.

Bit 2 / Receive Alarm Indication Signal Condition Detect (RAISD).

Rising edge detect of RAIS. Set when an

unframed all-ones code is received at RPOS and RNEG.

Bit 3 / Receive Remote Alarm Indication Condition Detect (RRAID).

Rising edge detect of RRAI. Set when a

remote alarm is received at RPOS and RNEG.

Bit 4 / Receive Loss-of-Frame Condition Clear (RLOFC).

Falling edge detect of RLOF. Set when an RLOF

condition has cleared.

Bit 5 / Receive Loss-of-Signal Condition Clear (RLOSC).

Falling edge detect of RLOS. Set when an RLOS

condition has cleared.

Bit 6 / Receive Alarm Indication Signal Condition Clear (RAISC).

Falling edge detect of RAIS. Set when a RAIS

condition has cleared.

Bit 7 / Receive Remote Alarm Indication Condition Clear (RRAIC).

Falling edge detect of RRAI. Set when a

RRAI condition has cleared.
