12 SW_INTERRUPT_FREQUENCY_TEST_01
This module contains functional safety diagnostics API for Interrupt Frequency Test.
- 12.1 Structs
- 12.2 Enums
- 12.3 Functions
  - 12.3.1 DIAG_INTERRUPT_Frequency
    This API is called at in RTC interrupt service routine. In this API monitors the frequency of registered interrupts by comparing the respective counter with reference considering the given tolerance. Interrupts are monitored only if those are registred and enabled for monitoring.
  - 12.3.2 DIAG_INTERRUPT_Register
    Software Requirement Reference ID : SW_INTERRUPT_FREQUENCY_TEST_01. For the GUID-C634F0A1-2432-44C1-997A-300BBE086CE9.html API to monitor the interrupt modules for frequency test, the modules are added to interrupt module structure using this API.
  - 12.3.3 DIAG_INTERRUPT_Unregister
    Software Requirement Reference ID : SW_INTERRUPT_FREQUENCY_TEST_01. This API is used to unregister an interrupt being monitored for the interrupt frequency. The interrupt identifier of the module which needs to be removed from being monitored for interrupt frequency, is passed as an argument to the API.
  - 12.3.4 DIAG_INTERRUPT_Initialize
    Software Requirement Reference ID : SW_INTERRUPT_FREQUENCY_TEST_01.
  - 12.3.5 DIAG_INTERRUPT_UpdateInterruptCounter
    Software Requirement Reference ID : SW_INTERRUPT_FREQUENCY_TEST_01. This API is used to increment the count of registered interrupt. This API should be called from ISR of registered interrupt.
  - 12.3.6 DIAG_INTERRUPT_GetStatus
    Software Requirement Reference ID : SW_INTERRUPT_FREQUENCY_TEST_01. This API is called to get the result of the respective interrupt module.
- 12.4 Variables
13 SW_SRAM_MARCH_TEST_01 - MarchC_Minus
This module contains functional safety diagnostics APIs for SRAM March-C Minus.
14 SW_WATCHDOG_SIMPLE_TIMER_STARTUP_TEST_01
This module contains functional safety diagnostics APIs for WatchDog Timer Test.
15 SW_WDT_WINDOWED_TIMER_STARTUP_TEST_01
This module contains functional safety diagnostics APIs for WatchDog Timer Test.
