Pin Description
I/O port with bit-programmable pins.
Configurable to input or push-pull output
mode. Pull-up resistors can be assigned
by software. Pins can also be assigned
individually as alternative function pins.
I/O I/O port with bit-programmable pins.
Configurable to input or push-pull output
mode. Pull-up resistors can be assigned
by software. Pins can also be assigned
individually as alternative function pins.
I/O I/O port with bit-programmable pins.
Configurable to input mode, push-pull
output mode. Input mode with pull-up
resistors can be assigned by software.
The port 2 pins have high current drive
capability. Pins can also be assigned
individually as alternative function pins.
