Function Documentation

void dmamux_hal_init ( uint8_t module )

Initializes the DMAMUX module to the reset state.

Parameters

module DMAMUX module index

static void dmamux_hal_enable_channel	(	uint8_t	module,
		uint8_t	channel
	)

inlinestatic

Enables the hardware request. If enabled, the hardware request is sent to the corresponding DMA channel.

Parameters

module	DMAMUX module.
channel	DMAMUX channel.

static void dmamux_hal_disable_channel	(	uint8_t	module,
		uint8_t	channel
	)

inlinestatic

Disable hardware request. If disabled, the hardware request is not sent to the corresponding DMA channel.

Parameters

module	DMAMUX module.
channel	DMAMUX channel.

static void dmamux_hal_enable_period_trigger	(	uint8_t	module,
		uint8_t	channel
	)

inlinestatic

Parameters

module	DMAMUX module.
channel	DMAMUX channel.

static void dmamux_hal_disable_period_trigger	(	uint8_t	module,
		uint8_t	channel
	)

inlinestatic

Parameters

module	DMAMUX module.
channel	DMAMUX channel.

static void dmamux_hal_set_trigger_source	(	uint8_t	module,
		uint8_t	channel,
		uint8_t	source
	)

inlinestatic

Sets the trigger source for the DMA channel. The trigger source is in the file fsl_dma_request.h.

Parameters
