Part 8 General Purpose Input/Output (GPIO)
8.1 Introduction
This section is intended to supplement the GPIO information found in the 56F8300 Peripheral User
Manual and contains only chip-specific information. This information supercedes the generic information
in the 56F8300 Peripheral User Manual.
8.2 Configuration
There are three GPIO ports defined on the 56F8323/56F8123. The width of each port and the associated
peripheral function is shown in
