External power and ground for I/O drivers and input to the internal voltage regulator. Because fast signal

transitions place high, short-duration current demands on the power supply, use bypass capacitors with

high-frequency characteristics and place them as close to the MCU as possible. Bypass requirements

depend on how heavily the MCU pins are loaded.

Power is supplied to the MCU through V

short-duration current demands on the power supply, use bypass capacitors with high-frequency

characteristics and place them as close to the MCU as possible. This 2.5-V supply is derived from the

internal voltage regulator. There is no static load on those pins allowed. The internal voltage regulator is

turned off, if V

Provides operating voltage and ground for the oscillator and the phased-locked loop. This allows the

supply voltage to the oscillator and PLL to be bypassed independently. This 2.5-V voltage is generated by

the internal voltage regulator.
