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 “Alternate Functions of Port D” on page

73.

AVCC

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

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

mended this pin is connected to VCC through a low-pass filter, as described in “Analog Noise

Canceling Techniques” on page 169.

The following pins receive their supply voltage from AVCC: PC7, PC[5:0] and (in 32-lead pack-

ages) PA[1:0]. All other I/O pins take their supply voltage from VCC.
