Receive Loopback Activation Code State
This READ ONLY bit indicates whether or not the Receive T1 Framer Block is
currently detecting the Receive Loopback Activation Code, as specified in the
Receive Loopback Activation Code Register (RLACR - address 0xn126) if
Receive Loopback Activation Code Detection is enabled.
0 = Indicates that the Receive T1 Framer Block is NOT currently detecting the
Receive Loopback Activation Code.
1 = Indicates that the Receive T1 Framer Block is currently detecting the
Receive Loopback Activation Code.

Receive Loopback Deactivation Code State
This READ ONLY bit indicates whether or not the Receive T1 Framer Block is
currently detecting the Receive Loopback Deactivation Code, as specified in
the Receive Loopback Deactivation Code Register (RLDCR - address
0xn127) if Receive Loopback Deactivation Code Detection is enabled.
0 = Indicates that the Receive T1 Framer Block is NOT currently detecting the
Receive Loopback Deactivation Code.
1 = Indicates that the Receive T1 Framer Block is currently detecting the
Receive Loopback Deactivation Code.

Change in Receive Loopback Activation Code interrupt Status
This Reset-Upon-Read bit field indicates whether or not the “Change in
Receive Loopback Activation Code” interrupt has occurred since the last read
of this register.
If this interrupt is enabled, then the Receive T1 Framer block will generate an
interrupt in response to either one of the following conditions.
1.
Whenever the Receive T1 Framer block detects the Receive Loopback
Activation Code.
2.
Whenever the Receive T1 Framer block no longer detects the Receive
Loopback Activation Code.
0 = Indicates that the “Change in Receive Loopback Activation Code” inter-
rupt has not occurred since the last read of this register
1 = Indicates that the “Change in Receive Loopback Activation Code” inter-
rupt has occurred since the last read of this register

0 = Indicates that the “Change in Receive Loopback Deactivation Code” inter-
rupt has not occurred since the last read of this register
