RL3
(real time)
RIR2.7
Receive Level Bit 3. See Table 7-2.
RL2

RIR2.6
Receive Level Bit 2. See Table 7-2.
RL1
(real time)
RIR2.5
Receive Level Bit 1. See Table 7-2.
RL0
(real time)
RIR2.4
Receive Level Bit 0. See Table 7-2.
n/a
RIR2.3
Not Assigned. Could be any value when read.
n/a
RIR2.2
Not Assigned. Could be any value when read.
ARLB
(real time)
RIR2.1
Automatic Remote LoopBack Detected. This bit will be set
to a one when the automatic Remote Loopback (RLB) circuitry
has detected the presence of a loop up code for 5 seconds. It
will remain set until the automatic RLB circuitry has detected
the loop down code for 5 seconds. See Section 6 for more
details. This bit will be forced low when the automatic RLB
circuitry is disabled (CCR6.5 = 0).
SEC
(latched)
RIR2.0
One Second Timer. This bit will be set to a one on one-second
boundaries as timed by the device based on the RCLK. It will
be cleared when read.
