IRQ Exported Functions
[IRQ]

Enables or disables a specific IRQ.

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.

Definition at line 165 of file SPIRIT_Irq.c.

Verifies if a specific IRQ has been generated.

The call resets all the IRQ status, so it can't be used in case of multiple raising interrupts.

Parameters:

xFlag

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

Return values:

SpiritBool

S_TRUE or S_FALSE.

Definition at line 273 of file SPIRIT_Irq.c.

Clear the IRQ status registers.

Parameters:

None.

Return values:

None.

Definition at line 256 of file SPIRIT_Irq.c.

De initializate the SpiritIrqs structure setting all the bitfield to 0.

Moreover, it sets the IRQ mask registers to 0x00000000, disabling all IRQs.

Parameters:

pxIrqInit

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

Return values:

None.

Definition at line 121 of file SPIRIT_Irq.c.

Fills a pointer to a structure of SpiritIrqs type reading the IRQ_MASK registers.

Parameters:

pxIrqMask

pointer to a variable of type SpiritIrqs, 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 SpiritIrqs. For example suppose that the Power On Reset and RX Data ready are the only enabled IRQs. SpiritIrqs myIrqMask; SpiritIrqGetStatus(&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.

Definition at line 221 of file SPIRIT_Irq.c.

Filla a pointer to a structure of SpiritIrqs type reading the IRQ_STATUS registers.

Parameters:

pxIrqStatus

pointer to a variable of type SpiritIrqs, 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 SpiritIrqs. For example suppose that the XO settling timeout is raised as well as the Sync word detection. SpiritIrqs myIrqStatus; SpiritIrqGetStatus(&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.

Definition at line 244 of file SPIRIT_Irq.c.

Enables all the IRQs according to the user defined pxIrqInit structure.

Parameters:

pxIrqInit

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

Return values:

None.
