Overview

The MCUXpresso SDK provides APIs for MCUXpresso SDK device's src operation.

The Power Management Unit(PMU) is designed to simplify the external power interface. Based on the features of PMU, the PMU driver is divided into 3 groups. In the function group "LDOs Control APIs", those APIs can be used to control LDOs (including PLL LDO, LPSR_DIG LDO, LPSR_ANA LDO) in software mode or hardware mode; In the function group "Bandgap Control APIs", those APIs can be used to control bandgap in software mode or hardware mode; In the function group "Body Bias Control APIs", those APIs can be used to control well bias and body bias in software mode or hardware mode.
