Functions of each port group (2/2)
To define the function and the electrical characteristics of a pin, several control
registers are provided.
• For a general description of the registers, see “Port Group Configuration
• For every port, detailed information on the configuration registers is given in
There are three types of control circuits, defined as port types. For a
description of the port types, see “Port Types Diagrams“ on page 52.
