Description

PLATFORM_PIN_FUNCTION_t describes the functions that the client wishes to assign to the pin.

PIN_FUNCTION_FLOATING: Unused during configuration. This indicates that the pin is currently unassigned.
PIN_FUNCTION_MISO: Configure for SPI MISO.
PIN_FUNCTION_MOSI: Configure for SPI MOSI.
PIN_FUNCTION_SCK: Configure for SPI SCK.
PIN_FUNCTION_SDA: Configure for I2C SDA.
PIN_FUNCTION_SCL: Configure for I2C SCK.
PIN_FUNCTION_DIGITAL_INPUT: Configure as a digital input.
PIN_FUNCTION_DIGITAL_OUTPUT: Configure as a digital output.
PIN_FUNCTION_ANALOG_INPUT: Configure as an analog input. This connects the pin to an ADC.
PIN_FUNCTION_ANALOG_OUTPUT: Configure as a digital output. This connects the pin to a DAC function or PWM function, depending upon pin capability.
PIN_FUNCTION_TX: Configure as an RS232 Tx signal.
PIN_FUNCTION_RX: Configure as an RS232 Rx signal.
PIN_FUNCTION_STATUS: Special configuration that is meaningful to the platform.
PIN_FUNCTION_ETHERNET_INPUT, PIN_FUNCTION_ETHERNET_OUTPUT: Configure for dedicated Ethernet function.
PIN_FUNCTION_MEMORY: Special configuration that implements an external memory bus.
