General Description
PTF3–PTF0 are general-purpose, bidirectional I/O port pins that contain higher current sink/source
capability.
PTF7–PTF0 are only available on the 64-pin QFP package. See
(TIM1), Chapter 18 Timer Interface Module (TIM2),
1.5.14 Port G I/O Pins (PTG7/AD23–PTBG0/AD16)
PTG7–PTG0 are general-purpose, bidirectional I/O port pins that can also be used for analog-to-digital
converter (ADC) inputs. PTG7–PTG0 are only available on the 64-pin QFP package. See
Input/Output (I/O) Ports
1.5.15 Unused Pin Termination
Input pins and I/O port pins that are not used in the application must be terminated. This prevents excess
current caused by floating inputs, and enhances immunity during noise or transient events. Termination
methods include:
Never connect unused pins directly to V
Since some general-purpose I/O pins are not available on all packages, these pins must be terminated
as well. Either method 1 or 2 above are appropriate.
28
1. Configuring unused pins as outputs and driving high or low;
2. Configuring unused pins as inputs and enabling internal pull-ups;
3. Configuring unused pins as inputs and using external pull-up or pull-down resistors.
