5.1 Contents
5.2 Introduction
The MCU can be reset from three sources: one external input and two
internal reset conditions. The RESET pin is an input with a Schmitt
trigger, as shown in Figure 5-1. The CPU and all peripheral modules will
be reset by the RST signal, which is the logical OR of internal reset
functions and is clocked by PH2.
