CONFIG_GPIO_MMIO32
¶
(No prompt – not directly user assignable.)
Type: bool
Help¶
This is a driver for accessing a simple, fixed purpose, 32-bit memory-mapped i/o register using the same APIs as GPIO drivers. This is useful when an SoC or board has registers that aren’t part of a GPIO IP block and these registers are used to control things that Zephyr normally expects to be specified using a GPIO pin, e.g. for driving an LED, or chip-select line for an SPI device.
Defaults¶
No defaults. Implicitly defaults to n
.
