- 9.1 Structs
- 9.2 Enums
- 9.3 Functions
  - 9.3.1 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.
  - 9.3.2 DIAG_INTERRUPT_Register
    This API registers an interrupt for diagnosis. When any interrupt is registered, diag_interrupt_params_t parameters are initialized with user defined values and are later updated or monitored by GUID-6710B17A-D9B8-4E77-B578-00E9FFDB4F96.html function.
  - 9.3.3 DIAG_INTERRUPT_Unregister
    This API unregisters an interrupt from frequency diagnosis.
  - 9.3.4 DIAG_INTERRUPT_Initialize
    This API configures the callback function for reference RTC periodic interrupt.
  - 9.3.5 DIAG_INTERRUPT_UpdateInterruptCounter
    This API increments the intr_counter for the registered interrupt.
  - 9.3.6 DIAG_INTERRUPT_GetStatus
    This API returns the result frequency diagnosis for required interrupt.
10 SRAM - Checkerboard Algorithm
This module contains functional safety diagnostics APIs for SRAM Checkerboard Test.
11 SRAM - March C-Minus Algorithm
This module contains functional safety diagnostics APIs for SRAM March-C Minus.
12 Simple Watchdog Timer
This module contains functional safety diagnostics APIs for WatchDog Timer Test.
13 Windowed Watchdog Timer
