While using a rotary encoder with ESP32-S3, I noticed both the high and low limits were returning to 0 on overflow, which is the default behavior of the ESP32 PCNT when the internal accumulator is disabled.
unit_config.flags.accum_count = true;
is set in the code, but watchpoints matching the high and low limits also need to be created for the internal accumulator to work.This PR should fix that.
