Description

GPIO0…31 output enable

Fields

GPIO_OE

Set output enable (1/0 -> output/input) for GPIO0…31. 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.

In the Non-secure SIO, Secure-only GPIOs (as per ACCESSCTRL) ignore writes, and their output status reads back as zero. This is also true for SET/CLR/XOR aliases of this register.
