3. Digital GPIO interface
The digital I/O (Input/Output) performance depends on its pad type, usage, and power supply voltage. The interfaces
of I2C, USB, SPI and UART are complied with their standards with no additional specifications. Performance
specifications for all other digital I/Os are organized in this section. The GPIOs can be programmed for a variety of
configurations.
