5.6 Behavior of the analog modules
5.6.1 Introduction
Overview
This section describes:
● How the analog input and output values depend on the operating states of the CPU and
the supply voltage of the analog module
● The reaction of analog modules, based on the actual analog value within the relevant
value range
● The effect of errors on analog modules with diagnostics capability
● The effect of the operational limit of the analog module on the analog input and output
value, as illustrated by an example
