FRAMER LOOPBACK
When CCR1.7 is set to a one, the framer will enter a Framer LoopBack (FLB) mode. See Figure 6–1 for
more details. This loopback is useful in testing and debugging applications. In FLB, the framer will loop
data from the transmit side back to the receive side. When FLB is enabled, the following will occur:
1) Data will be transmitted as normal at TPOS and TNEG.
2) Data input by RPOS and RNEG will be ignored.
3) The RCLK output will be replaced with the TCLK input.
