4.4.2 Functions

static uint16_t abs_diff (uint16_t a, uint16_t b)

static void DIAG_INT_Frequency (void)

diag_result_t DIAG_INT_FrequencyRegister (diag_int_id_t intId, uint16_t refCount, uint16_t tolerance, uint16_t fdtiCount)

Registers an interrupt source to monitor. When any interrupt is registered, diag_int_params_t parameters are initialized with user-defined values and are later updated or monitored by DIAG_INT_Frequency function.

diag_result_t DIAG_INT_FrequencyUnregister (diag_int_id_t intId)

Unregisters an interrupt from the frequency diagnosis.

void DIAG_INT_FrequencyCountInterrupt (diag_int_id_t intId)

Increments the intr_counter for the registered interrupt.

void DIAG_INT_FrequencyInitialize (void)

Configures the callback function for reference RTC periodic interrupt.

bool DIAG_INT_FrequencyIsResultReady (diag_int_id_t intId)

Returns the interrupt diagnosis status.

diag_result_t DIAG_INT_FrequencyGetResult (diag_int_id_t intId)

Returns the required interrupt frequency diagnosis. The result is set to DIAG_UNDEFINED after returning PASS or FAIL to ensure that the latest result from the diagnostic is returned.
