The XC87x microcontroller requires two different levels of power supply:

must be provided from the external power supply pin. The 2.5 V power supply for the
logic is generated by the EVR. The EVR helps to reduce the power consumption of the
whole chip and the complexity of the application board design.
The EVR consists of a main voltage regulator and a low power voltage regulator. In
active mode, both voltage regulators are enabled. In power-down mode
voltage regulator is switched off, while the low power voltage regulator continues to
function and provide power supply to the system with low power consumption.
