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

Bit 7: Receive Remote Alarm Indication Condition Clear (RRAIC). Falling edge detect of RRAI. Set when a

RRAI 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 5: Receive Loss of Signal Condition Clear (RLOSC). Falling edge detect of RLOS. Set when an RLOS

condition has cleared.

Bit 4: Receive Loss of Frame Condition Clear (RLOFC). Falling edge detect of RLOF. Set when an RLOF

condition has cleared.

Bit 3: Receive Remote Alarm Indication Condition Detect (RRAID). Rising edge detect of RRAI. Set when a

remote alarm is received at RTIP and RRING.

Bit 2: Receive Alarm Indication Signal Condition Detect (RAISD). Rising edge detect of RAIS.Set when an

unframed all-ones code is received at RTIP and RRING.

Bit 1: Receive Loss of Signal Condition Detect (RLOSD). Rising edge detect of RLOS. Set when 192

consecutive zeros have been detected at RTIP and RRING.

Bit 0: Receive Loss of Frame Condition Detect (RLOFD). Rising edge detect of RLOF. Set when the DS26521

has lost synchronized to the received data stream.
