INT0
P0.0
Bit-programmable I/O port for Schmitt trigger
input or n-ch open drain output (50 mA).
Pull-up resistor is assignable to input pin by
software and is automatically disabled for
output pin. Port 0 can be individually configured
as external interrupt input.
Bit-programmable I/O port for Schmitt trigger
input or push-pull output. Pull-up resistors
individually assignable to input pins by software
and are automatically disabled for output pins.
Port 0 can be individually configured as
external interrupt inputs.
Bit-programmable I/O port for Schmitt trigger
input or push-pull output. Pull-up resistors are
individually assignable to input pins by
software. Port 1 can be configured as
comparator input or external interrupt inputs.
Pull-down resistors are individually assignable.
(in comparator input)
Bit-programmable I/O port for Schmitt trigger
input or n-ch open drain output. Pull-up
resistors are individually assignable to input
pins by software and are automatically disabled
for output pins. Port 2 can be individually
configured as external interrupt inputs. Also it
can be configured as an USB ports.
