Detailed Description

Overview

The GPIO Driver Library allows full configuration of the MSPM0 GPIO module. The GPIO peripheral provides the user with a means to write data out and read data in to and from the device pins. It also provides a way to detect wakeup events while the device is in a low power state.

	)

Disable GPIO events.

Parameters

[in]	gpio	Pointer to the register overlay for the peripheral
[in]	index	Specifies the register event index to be configured
[in]	pins	Valid options will depend on index argument. When index == DL_GPIO_EVENT_ROUTE_1, valid pins values are bitwise OR of DL_GPIO_PIN (0-15). When index == DL_GPIO_EVENT_ROUTE_2, valid pins Bitwise OR of DL_GPIO_PIN (16-31).

§ DL_GPIO_getEnabledEvents()

__STATIC_INLINE uint32_t DL_GPIO_getEnabledEvents	(	GPIO_Regs *	gpio,
		DL_GPIO_EVENT_ROUTE	index,
		uint32_t	pins
	)

Check which GPIO events are enabled.

Parameters

[in]	gpio	Pointer to the register overlay for the peripheral
[in]	index	Specifies the register event index to be configured
[in]	pins	Valid options will depend on index argument. When index == DL_GPIO_EVENT_ROUTE_1, valid pins values are bitwise OR of DL_GPIO_PIN (0-15). When index == DL_GPIO_EVENT_ROUTE_2, valid pins Bitwise OR of DL_GPIO_PIN (16-31).

Returns: Which of the requested GPIO events are enabled

Return values

Bitwise OR of DL_GPIO_PIN values

§ DL_GPIO_getEnabledEventStatus()

__STATIC_INLINE uint32_t DL_GPIO_getEnabledEventStatus	(	GPIO_Regs *	gpio,
		DL_GPIO_EVENT_ROUTE	index,
		uint32_t	pins
	)

Checks if any of the GPIO events which were previously enabled are pending.

Parameters

[in]	gpio	Pointer to the register overlay for the peripheral
[in]	index	Specifies the register event index to be configured
[in]	pins	Valid options will depend on index argument. When index == DL_GPIO_EVENT_ROUTE_1, valid pins values are bitwise OR of DL_GPIO_PIN (0-15). When index == DL_GPIO_EVENT_ROUTE_2, valid pins Bitwise OR of DL_GPIO_PIN (16-31).

Returns: Which of the requested GPIO events are pending

Return values

Bitwise OR of DL_GPIO_PIN values

	)

Clear pending GPIO event.

Parameters

[in]	gpio	Pointer to the register overlay for the peripheral
[in]	index	Specifies the register event index to be configured
[in]	pins	Valid options will depend on index argument. When index == DL_GPIO_EVENT_ROUTE_1, valid pins values are bitwise OR of DL_GPIO_PIN (0-15). When index == DL_GPIO_EVENT_ROUTE_2, valid pins Bitwise OR of DL_GPIO_PIN (16-31).
