void LL_LPTIM_Disable

(

LPTIM_TypeDef *

LPTIMx

)

Disable the LPTIM instance.

Reference Manual to LL API cross reference:

CR ENABLE LL_LPTIM_Disable

Parameters:

LPTIMx

Low-Power Timer instance

Note:

The following sequence is required to solve LPTIM disable HW limitation. Please check Errata Sheet ES0335 for more details under "MCU may remain stuck in LPTIM interrupt when entering Stop mode" section.

Return values:

None

ErrorStatus LL_LPTIM_Init	(	LPTIM_TypeDef *	LPTIMx,
		LL_LPTIM_InitTypeDef *	LPTIM_InitStruct
	)

Configure the LPTIMx peripheral according to the specified parameters.

Note:

LL_LPTIM_Init can only be called when the LPTIM instance is disabled.

LPTIMx can be disabled using unitary function LL_LPTIM_Disable().

Parameters:

LPTIMx	LP Timer Instance
LPTIM_InitStruct	pointer to a LL_LPTIM_InitTypeDef structure

Return values:

An	ErrorStatus enumeration value: SUCCESS: LPTIMx instance has been initialized ERROR: LPTIMx instance hasn't been initialized

void LL_LPTIM_StructInit

(

LL_LPTIM_InitTypeDef *

LPTIM_InitStruct

)

Set each fields of the LPTIM_InitStruct structure to its default value.

Parameters:

LPTIM_InitStruct

pointer to a LL_LPTIM_InitTypeDef structure

Return values:

None
