4.3.2 CTS Operation principle
The current circuit supervision function can be enabled or disabled by setting the corresponding
CTS_Ena parameter value as "1" or "0".
The operation of current circuit supervision can be described by using a module diagram. All the
modules in the diagram are explained in the next sections.
