I/O pins offer flexibility for a variety of
connections. The CC13x1x3 and
CC26x1x3 device platform supports highly
configurable I/O pins that can be multiplexed to any digital peripheral through the
I/O Controller.
Note: Analog functionality and high-drive strength is
limited to certain pins. See Chapter 13 for details.
- Up to 31 GPIOs, depending on configuration
- Up to five 8 mA drive strength pins
- Fully flexible digital pin muxing allows use as GPIO or any of several peripheral functions
- Programmable control for GPIO interrupts:
- Interrupt generation masking per pin
- Edge-triggered on rising or falling
- Bit masking in read and write operations through address lines
- Can initiate a μDMA transfer
- Pin state can be retained during all sleep modes
- Pins configured as digital inputs are Schmitt-triggered
- Programmable control for DIO configuration:
- Weak pullup or pulldown resistors
- Digital input enables
