Texas Instruments Tiva TM4C123GH6PM User Manual

GPIO
ui8Pins is the bit-packed representation of the pin(s).
Description:
This function disables a GPIO pin to be used as a trigger to start an ADC se-
quence. This function can be used to disable this feature if it was enabled via a call to
ROM_GPIOADCTriggerEnable().
Returns:
None.
10.2.1.2 ROM_GPIOADCTriggerEnable
Enables a GPIO pin as a trigger to start an ADC capture.
Prototype:
void
ROM_GPIOADCTriggerEnable(uint32_t ui32Port,
uint8_t ui8Pins)
ROM Location:
ROM_APITABLE is an array of pointers located at 0x0100.0010.
ROM_GPIOTABLE is an array of pointers located at ROM_APITABLE[4].
ROM_GPIOADCTriggerEnable is a function pointer located at ROM_GPIOTABLE[33].
Parameters:
ui32Port is the base address of the GPIO port.
ui8Pins is the bit-packed representation of the pin(s).
Description:
This function enables a GPIO pin to be used as a trigger to start an ADC sequence. Any GPIO
pin can be configured to be an external trigger for an ADC sequence. The GPIO pin will still
generate interrupts if the interrupt is enabled for the selected pin.
Returns:
None.
10.2.1.3 ROM_GPIODirModeGet
Gets the direction and mode of a pin.
Prototype:
uint32_t
ROM_GPIODirModeGet(uint32_t ui32Port,
uint8_t ui8Pin)
ROM Location:
ROM_APITABLE is an array of pointers located at 0x0100.0010.
ROM_GPIOTABLE is an array of pointers located at ROM_APITABLE[4].
ROM_GPIODirModeGet is a function pointer located at ROM_GPIOTABLE[2].
