Detailed Description

The interrupt test checks functionality of NVIC.

Providing an intermediate vector which is used to check the occurrence of an
interrupt the original vector can be configured, so interrupts can be simulated

Function Documentation

void IEC60335_ClassB_InitInterruptTest	(	IRQn_Type	IRQn,
		uint8_t	Mode,
		IRQTestData_t *	CountSetup
	)

Initialization of a specified interrupt test.

Parameters:

IRQn	number of the interrupt to test if number smaller than "SysTick_IRQn" the function deactivates all tests numbers bigger than "PendSV_IRQn" activates the test calling a second time with the same IRQn will deactivate this test
Mode	configure interrupt is calling the original handler
CountSetup	counters of interrupt occurrences

Note:

The interrupt test is deactivated when called with a exception number (< SysTick_IRQn) on the IRQn parameter. In this case the original vector table is restored and all flags are deleted.

Attention:

Ensure to place the function call #IEC60335_ClassB_InterruptOcurred into the corresponding interrupt service handler!

The interrupt check routine must be called once in known equidistant times.

Attention:

If this function is disturbed by active tested interrupts, the result counter may be out of range.

Parameters:

IRQn	number of the interrupt to test

Returns:

passed or failed. See testResult_t .

Here is the caller graph for this function:

void IEC60335_IRQReplacementHandler

(

void

)

call the original vector

Parameters:

vect

IRQ index

Interrupt replacement handler to check interrupt occurrences

Note:

The interrupt test requires an intermediate call and work on the test data. To achieve this goal the replacement handler is called instead of the user handler. If the corresponding Mode flag is set the routine calls the original vector handler.
