Appendix A Electrical Characteristics
A.1.3
There are four groups of functional pins.
A.1.3.1
Those I/O pins have a nominal level of 5V. This class of pins is comprised of all port I/O pins, the analog
inputs, BKGD pin, and the RESET inputs.The internal structure of all those pins is identical; however
some of the functionality may be disabled. For example, pull-up and pull-down resistors may be disabled
permanently.
A.1.3.2
This class is made up by the two V
bonded to the V
A.1.3.3
The pins XFC, EXTAL, XTAL dedicated to the oscillator have a nominal 2.5V level. They are supplied by
V
A.1.3.4
This pin is used for production testing only.
A.1.4
