UART2 data output pin
This function is available when UART2 data output is enabled.
PWM timer output pin
This function is available when PWM timer output is enabled.
Can be configured as the I/O port when SO2 and OCPA2 are
not used.
This function is available when UART2 data output is disabled.
PWM timer output pin
This function is available when PWM timer output is enabled.
Can be configured as the I/O port when OCPA0 and ATG are
not used.
This function is available when PWM timer output is disabled.
External trigger input pin for A/D converter
This pin is used for input when external trigger is selected to
cause A/D converter operation, and it is necessary to disable
output for other functions from this pin unless such output is
made intentionally.
Analog input pins of A/D converter
Power supply pin (V
Reference voltage input (high) for A/D converter
Make sure to turn on and off this pin with potential of AVRH or
more applied to AV
Power supply pin (V
input pin (low)
5 V power supply pin (V
Always two pins must be connected to the power supply (con-
nect to 3 V power supply when operating at 3 V).
Bypass capacitor pin for internal capacitor.
Also connect this pin to 3 V power supply when operating at
3 V.
