externally pulled low will source current if the pull-up resistors are activated. The Port D pins are
tri-stated when a reset condition becomes active, even if the clock is not running.
The various special features of Port D are elaborated in

AV
is the supply voltage pin for the A/D converter and a selection of I/O pins. This pin should

be externally connected to V
even if the ADC is not used. If the ADC is used, it is recom-

Canceling Techniques” on page
169.
The following pins receive their supply voltage from AV
: PC7, PC[5:0] and (in 32-lead pack-
