MCU Electrical Specifications
A.1.2
There are four groups of functional pins.
A.1.2.1
The I/O pins have a level in the range of 3.13V to 5.5V. This class of pins is comprised of all port I/O pins,
the analog inputs, BKGD and the RESET pins. Some functionality may be disabled.
A.1.2.2
LS[1:0], HS[1:0], PL[3:0], VSENSE have a nominal 12V level.
A.1.2.3
The pins EXTAL, XTAL dedicated to the oscillator have a nominal 1.8V level.
A.1.2.4
This pin is used for production testing only. The TEST pin must be tied to ground in all applications.
