AN921 is Configurable Logic Unit manufactured by Silicon Labs.
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 binatorial logic functions, such as AND, OR, XOR, and multiplexing.
- Multiple units bined can implement latches, encoders, and decoders.
