Receive Level Bit 0. See
Not Assigned. Could be any value when read.
Not Assigned. Could be any value when read.
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
when the automatic RLB circuitry is disabled (CCR6.5 = 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.
