GPIO
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_GPIOPinWrite is a function pointer located at ROM_GPIOTABLE[0].
Parameters:
ui32Port is the base address of the GPIO port.
ui8Pins is the bit-packed representation of the pin(s).
ui8Val is the value to write to the pin(s).
Description:
Writes the corresponding bit values to the output pin(s) specified by ui8Pins. Writing to a pin
configured as an input pin has no effect.
The pin(s) are specified using a bit-packed byte, where each bit that is set identifies the pin to
be accessed, and where bit 0 of the byte represents GPIO port pin 0, bit 1 represents GPIO
port pin 1, and so on.
Returns:
None.
