P80,
P81
G
General-purpose I/O port
This function is always valid.
INT0,
INT1
DTP/external interrupt input pin
When external interrupts are enabled, these inputs may be
used at any time; therefore, it is necessary to stop output by
other functions on this pin, except when using them for output
deliberately.
51
P82
G
General-purpose I/O port
This function is always valid.
INT2
DTP/external interrupt input pin
When external interrupts are enabled, these inputs may be
used at any time; therefore, it is necessary to stop output by
other functions on this pin, except when using them for output
deliberately.
Because an input to this pin is clamped to Low when the CPU
stops, use INT0 or INT1 to wake up the system from the stop
mode.
ATG
8/10-bit A/D converter trigger input pin
When 8/10-bit A/D converter is waiting for activation, this input
may be used at any time; therefore, it is necessary to stop
output by other functions on this pin, except when using it for
output deliberately.
52
CLK
G
CLK output pin
RY/BY
Open-drain pin output ready/busy signal in the program deleting
operation
This function is valid in the flash memory mode.

Digital circuit power supply (GND) pin
26
AVCC
Power
supply
Analog circuit power supply pin
This power supply must only be turned on or off when electric
potential of AVCC or greater is applied to VCC.
27
AVRH
Power
supply
8/10-bit A/D converter external reference voltage input pin
This pin must only be turned on or off when electric potential of
AVRH or greater is applied to AVCC.
