Function Documentation

static void TRGMUX_LockRegister ( TRGMUX_Type *  base, uint32_t  index  )

inlinestatic

The function sets the flag of the register which is used to mark writeable. Example:

TRGMUX_LockRegister(TRGMUX0,kTRGMUX_Trgmux0Dmamux0);

Parameters

base	TRGMUX peripheral base address.
index	The index of the TRGMUX register, see the enum trgmux_device_t defined in <SOC>.h.

status_t TRGMUX_SetTriggerSource	(	TRGMUX_Type *	base,
		uint32_t	index,
		trgmux_trigger_input_t	input,
		uint32_t	trigger_src
	)

The function configures the trigger source of the appointed peripheral. Example:

TRGMUX_SetTriggerSource(TRGMUX0, kTRGMUX_Trgmux0Dmamux0, kTRGMUX_TriggerInput0, kTRGMUX_SourcePortPin);

Parameters

base	TRGMUX peripheral base address.
index	The index of the TRGMUX register, see the enum trgmux_device_t defined in <SOC>.h.
input	The MUX select for peripheral trigger input
trigger_src	The trigger inputs for various peripherals. See the enum trgmux_source_t defined in <SOC>.h.

Return values

kStatus_Success	Configured successfully.
kStatus_TRGMUX_Locked	Configuration failed because the register is locked.
