GPIO output enable

Type Aliases§

  • Field GPIO_OE reader - Set output enable (1/0 -> output/input) for GPIO0…29.
    Reading back gives the last value written.
    If core 0 and core 1 both write to GPIO_OE simultaneously (or to a SET/CLR/XOR alias),
    the result is as though the write from core 0 took place first,
    and the write from core 1 was then applied to that intermediate result.
  • Field GPIO_OE writer - Set output enable (1/0 -> output/input) for GPIO0…29.
    Reading back gives the last value written.
    If core 0 and core 1 both write to GPIO_OE simultaneously (or to a SET/CLR/XOR alias),
    the result is as though the write from core 0 took place first,
    and the write from core 1 was then applied to that intermediate result.
