Bit 7: Receive Yellow Alarm Clear Event (RYELC) (T1 Only). Set when the receive Yellow Alarm condition is no
longer detected.
Bit 6: Receive Unframed All-Ones Clear Event (RUA1C). Set when the unframed all 1s condition is no longer
detected.
Bit 5: Framer Receive Carrier-Loss Clear Event (FRCLC). Set when the carrier loss condition at RPOSI and
RNEGI is no longer detected.
Bit 4: Receive Loss-of-Sync Clear Event (RLOSC). Set when the framer achieves synchronization; remains set
until read.
