7.2 FRAMER LOOPBACK
When CCR1.7 is set to a one, the DS21Q50 will enter a Framer LoopBack (FLB) mode. See Figure
4-1
for
more details. This loopback is useful in testing and debugging applications. In FLB, the SCT will loop data from
the transmitter back to the receiver. 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.
