NOTE:
PTC1–PTC0 are general-purpose, bidirectional I/O port pins. See
Input/Output Ports
QFP packages.
These port pins also have selectable pullups when configured for input
mode. The pullups are disengaged when configured for output mode.
The pullups are selectable on an individual port bit basis.
PTD6–PTD0 are special-function, bidirectional I/O port pins.
PTD3–PTD0 can be programmed to be serial peripheral interface (SPI)
pins, while PTD6–PTD4 can be individually programmed to be timer
interface module (TIM1 and TIM2) pins. See
(TIM),
These port pins also have selectable pullups when configured for input
mode. The pullups are disengaged when configured for output mode.
The pullups are selectable on an individual port bit basis.
When the port pins are configured for special-function mode (SPI, TIM1,
TIM2), pullups can be selectable on an individual port pin basis.
PTE1–PTE0 are special-function, bidirectional I/O port pins. These pins
can also be programmed to be serial communications interface (SCI)
pins. See
(I/O).
Any unused inputs and I/O ports should be tied to an appropriate logic
level (either V
do not require termination, termination is recommended to reduce the
possibility of electro-static discharge damage.
