From b5198201932635e19068cc2e83a99adf38f32c43 Mon Sep 17 00:00:00 2001 From: William Breathitt Gray Date: Thu, 6 Mar 2025 16:05:43 +0900 Subject: counter: Introduce the compare component Compare registers are used in devices to compare a counter channel against a particular count value (e.g. to check if a threshold has been reached). A macro COUNTER_COMP_COMPARE() is introduced to facilitate the creation of compare components as Count extensions.
