4.11.2.3 GPIO
All digital pins of the device can be used as general-purpose input/output (GPIO) pins.The GPIO module
consists of four GPIO blocks, each of which provides eight GPIOs. The GPIO module supports 24
programmable GPIO pins, depending on the peripheral used. Each GPIO has configurable pullup and
pulldown strength (weak 10 µA), configurable drive strength (2, 4, and 6 mA), and open-drain enable.
Figure 4-13 shows the GPIO timing diagram.
