LOCAL LOOPBACK
When CCR1.0 is set to a 1, the DS2141A will enter a Local LoopBack (LLB) mode. This loopback is
useful in testing and debugging applications. In LLB, the DS2141A will loop data from the transmit side
back to the receive side. This loopback is synonymous with replacing the RCLK input with the TCLK
signal, and the RPOS/RNEG inputs with the TPOS/TNEG outputs. When LLB is enabled, the following
will occur:
1. The TPOS and TNEG pins will transmit an unframed all 1's.
2. Data at RPOS and RNEG will be ignored.
3. All receive side signals will take on timing synchronous with TCLK instead of RCLK.
