25.1 Overview
Preliminary User’s Manual U17566EE1V2UM00
The microcontroller has general power supply pins for its core, internal
memory and peripherals. These pins are connected to internal voltage
regulators. The microcontroller also has dedicated power supply pins for
certain I/O modules. These pins provide the power for the I/O operations.
The following table gives the naming convention of the pins:
