1.4.43
External power and ground for I/O drivers. Bypass requirements depend on how heavily the MCU pins are
loaded.
1.4.44
External power and ground for I/O drivers and input to the internal voltage regulator. Bypass requirements
depend on how heavily the MCU pins are loaded.
1.4.45
Power is supplied to the MCU through VDD and VSS. This 2.5V 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 VDDR is tied to ground.
1.4.46
VDDA, VSSA are the power supply and ground input pins for the voltage regulator and the analog to
digital converter.
1.4.47
VRH and VRL are the reference voltage input pins for the analog to digital converter.
1.4.48
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 2.5V voltage is generated by
the internal voltage regulator.
