S2LPGpioInit()

void S2LPGpioInit

(

SGpioInit *

pxGpioInitStruct

)

Parameters

pxGpioInitStruct

pointer to a SGpioInit structure that contains the configuration information for the specified S2LP GPIO.

Return values

None.

S2LPGpioIrqCheckFlag()

SBool S2LPGpioIrqCheckFlag

(

IrqList

xFlag

)

Parameters

xFlag

IRQ flag to be checked. This parameter can be any value of IrqList.

Return values

SBool

S_TRUE or S_FALSE.

Parameters

None.

Return values

None.

S2LPGpioIrqConfig()

void S2LPGpioIrqConfig	(	IrqList	xIrq,
		SFunctionalState	xNewState
	)

Parameters

xIrq	IRQ to enable or disable. This parameter can be any value of IrqList.
xNewState	new state for the IRQ. This parameter can be: S_ENABLE or S_DISABLE.

Return values

None.

S2LPGpioIrqDeInit()

void S2LPGpioIrqDeInit

(

S2LPIrqs *

pxIrqInit

)

Parameters

pxIrqInit

pointer to a variable of type S2LPIrqs, in which all the bitfields will be settled to zero.

Return values

None.

S2LPGpioIrqGetMask()

void S2LPGpioIrqGetMask

(

S2LPIrqs *

pxIrqMask

)

Parameters

pxIrqMask

pointer to a variable of type S2LPIrqs, through which the user can read which IRQs are enabled. All the bitfields equals to zero correspond to enabled IRQs, while all the bitfields equals to one correspond to disabled IRQs. This parameter is a pointer to a S2LPIrqs. For example suppose that the Power On Reset and RX Data ready are the only enabled IRQs. S2LPIrqs myIrqMask; S2LPIrqGetStatus(&myIrqMask); Then myIrqMask.IRQ_POR and myIrqMask.IRQ_RX_DATA_READY are equal to 0 while all the other bitfields are equal to one.

Return values

None.

S2LPGpioIrqGetStatus()

void S2LPGpioIrqGetStatus

(

S2LPIrqs *

pxIrqStatus

)

Parameters

pxIrqStatus

pointer to a variable of type S2LPIrqs, through which the user can read the status of all the IRQs. All the bitfields equals to one correspond to the raised interrupts. This parameter is a pointer to a S2LPIrqs. For example suppose that the XO settling timeout is raised as well as the Sync word detection. S2LPIrqs myIrqStatus; S2LPGpioIrqGetStatus(&myIrqStatus); Then myIrqStatus.IRQ_XO_COUNT_EXPIRED and myIrqStatus.IRQ_VALID_SYNC are equals to 1 while all the other bitfields are equals to zero.

Return values

None.

S2LPGpioIrqInit()

void S2LPGpioIrqInit

(

S2LPIrqs *

pxIrqInit

)

Parameters

pxIrqInit

pointer to a variable of type S2LPIrqs, through which the user enable specific IRQs. This parameter is a pointer to a S2LPIrqs. For example suppose to enable only the two IRQ Low Battery Level and Tx Data Sent: S2LPIrqs myIrqInit = {0}; myIrqInit.IRQ_LOW_BATT_LVL = 1; myIrqInit.IRQ_TX_DATA_SENT = 1; S2LPGpioIrqInit(&myIrqInit);

Return values

None.

xLevel	Specifies the level. This parameter can be: HIGH or LOW.

Return values

None.
