FRAMER LOOPBACK
When CCR1.0 is set to a 1, the DS21Q41B will enter a Framer LoopBack (FLB) mode. This loopback is
useful in testing and debugging applications. In FLB, the DS21Q41B will loop data from the transmit
side back to the receive side. When FLB is enabled, the following will occur:
1. An unframed all 1s code will be transmitted at TPOS and TNEG.
2. Data at RPOS and RNEG will be ignored.
3. All receive side signals will take on timing synchronous with TCLK instead of RCLK.
