I/O Pin Characteristics
Notes:
1. V
VDD
corresponds to either V
VDDIN
or V
VDDIO
, depending on the supply for the pin. Refer to
for details.
2. These values are based on simulation and characterization of other AVR microcontrollers manufactured in the same pro-
cess technology. These values are not covered by test limits in production.
