AN921: Configurable Logic Unit The EFM8LB1 and EFM8BB3 family of MCUs contain Configurable Logic Units (CLUs) that can be applied to applications that require some form of programmable logic.
This document demonstrates how to use CLUs to implement the following functions: • SR latch • D latch • Button debounce • Manchester encoder/decoder • Biphase Mark encoder/decoder KEY POINTS • Configurable Logic operates without CPU intervention.
• Each unit supports 256 different combinatorial logic functions, such as AND, OR, XOR, and multiplexing.
• Multiple units combined can implement latches, encoders, and decoders.
