Table 2-7 describes the pinouts for the six available GPIOs.

Table 2-7 Pin Description
Pin Name Comment
1 GPIO1 Multifunction push-pull pin, general-purpose digital input or general-purpose digital output.
2 PLSR_GPIO2 Multifunction push-pull pin, general-purpose digital input or general-purpose digital output.
3 GPIO3 Multifunction open drain pin, general-purpose digital input or general-purpose digital output.
4 GPIO4 LED display segment that drives the external LEDs via an internal current sink depending on the firmware configuration. Alternatively, this pin is push-pull and can be configured as a general-purpose digital input or general-purpose digital output pin.
5 GPIO5 LED display segment that drives the external LEDs via an internal current sink depending on the firmware configuration. Alternatively, this pin is push-pull and can be configured as a general-purpose digital input or general-purpose digital output pin.
6 GPIO6 LED display segment that drives the external LEDs via an internal current sink depending on the firmware configuration. Alternatively, this pin is push-pull and can be configured as a general-purpose digital input or general-purpose digital output pin.
