AN921: Configurable Logic Unit
Biphase Mark Encoder/Decoder
6.3 Biphase Mark Decoder
In this section, we will demonstrate how to use the CLUs, Timers, and SPI to decode the data with little CPU intervention. The example
will receive a BMC-encoded signal at 300 kbps with the system clock operating at 24.5 MHz. This section also demonstrates how to
use the CLUs and Timers to perform clock recovery of the signal.
