AN921 Configurable Logic Unit

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 • But.

Rev. 0.1 AN921: Configurable Logic Unit Configurable Logic Overview 1. Configurable Logic Overview The configurable logic module provides multiple blocks of user-programmed digital logic that operate without CPU intervention. In the EFM8LB1 and EFM8BB3 families, the configurable logic (CL) module contains of four independent configurable logic units (CLUs) that support user-programmable asynchronous and synchronous .
