Framer Loopback
When CCR1.7 is set to one, the DS21354/DS21554 enter a framer loopback (FLB) mode. See Figure 2-1
for more details. This loopback is useful in testing and debugging applications. In FLB, the SCT 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 TPOSO and TNEGO.
2) Data input via RPOSI and RNEGI will be ignored.
3) The RCLK output will be replaced with the TCLK input.
