10.1
When developing an application, the capabilities of the
port pins must be considered. Outputs on some pins
have higher output drive strength than others. Similarly,
some pins can tolerate higher than V
10.1.1
General purpose output buffers are implemented with
CMOS transistors, for rail to rail output capability, when
lightly loaded. The output pin drive strengths vary for
groups of pins intended to meet the needs for a variety
of applications. PORTB and PORTC are designed to
drive higher loads, such as LEDs. All other ports are
designed for small loads; typically, indication only.

10.1.2
The voltage tolerance of pins used as device inputs is
dependent on the pin’s input function. Pins that are used
as digital only inputs are able to handle DC voltages up to
5.5V; a level typical for digital logic circuits. In contrast,
pins that also have analog input functions of any kind can
only tolerate voltages up to V
