RST
Reset I/O pin.
This pin serves as an N-channel open-drain output with pull-up
C
resistor and a hysteresis input as well. The pin outputs the “L”
signal (optionally) in response to an internal reset request. Also,
it initializes the
internal circuit upon input of the “L” signal.
General-purpose CMOS I/O ports.

G
These pins also serve as an input (wake-up input) of external in-
terrupt 2 or as an A/D converter analog input. The input of ex-
ternal interrupt 2 is a hysteresis input.

P34/TO/INT10
D
This pin also serves as the output pin for the 8/16-bit capture tim-
er/counter or as the input pin for external interrupt 1. The re-
source is a hysteresis input.

General-purpose CMOS I/O ports.
D These pins also serve as the input pin for external
interrupt 1. The resource is a hysteresis input.
