3 PIC16 Diagnostic Test APIs
- 3.1 SW_CPU_REGISTER_RESET_STATE_CHECK_01
  This module contains functional safety diagnostics APIs for CPU Registers.
- 3.2 SW_CLOCK_PERIODIC_MONITOR_01
  Software Requirement ID: SW_CLOCK_PERIODIC_MONITOR_01 This module contains APIs to calculate and validate the frequency of the CPU clock using a reference Secondary Oscillator Crystal. It verifies the reliability of the system clock (i.e., the system clock should be neither too fast nor too slow)
- 3.3 SW_CLOCK_PERIODIC_MONITOR_02
  Software Requirement ID: SW_CLOCK_PERIODIC_MONITOR_02. This module contains APIs to calculate, store and validate the frequency of the CPU clock using a reference line frequency.
- 3.4 SW_CPU_REGISTER_TEST_01
  This module contains functional safety diagnostics APIs for CPU Registers.
- 3.5 SW_EEPROM_MEMORY_CHECKSUM_CRC_TEST_01 - CRC16
  This module contains APIs to calculate, store and validate 16-bit CCITT CRC for a given EEPROM region.
- 3.6 SW_EEPROM_MEMORY_CHECKSUM_CRC_TEST_01 - CRC32
  This module contains APIs to calculate, store and validate 32-bit CCITT CRC for a given EEPROM region.
- 3.7 SW_FLASH_MEMORY_CHECKSUM_CRC_TEST_01 - CRC16
  This module contains APIs to calculate, store and validate 16-bit CCITT CRC for a given FLASH region.
- 3.8 SW_FLASH_MEMORY_CHECKSUM_CRC_TEST_01 - CRC32
  This module contains APIs to calculate, store and validate 32-bit CCITT CRC for a given FLASH region.

    - 3.9.3.1 DIAG_INTERRUPT_Frequency
      Software Requirement Reference ID : SW_INTERRUPT_FREQUENCY_TEST_01.
    - 3.9.3.2 DIAG_INTERRUPT_Register
      For the GUID-572720E4-FD0D-45DA-8399-D18FA6A29E49.html API to monitor the interrupt modules for frequency test, the modules are added to interrupt module structure using this API.
    - 3.9.3.3 DIAG_INTERRUPT_Initialize
      For the interrupt frequency test, the module interrupts parameters are stored in an internal structure. This API initializes that structure.
    - 3.9.3.4 DIAG_INTERRUPT_UpdateInterruptCounter
      This API is called from the ISR from where the API updates the internally maintained interrupt module structure for the respective interrupt module, identified by the interrupt identifier.
    - 3.9.3.5 DIAG_INTERRUPT_GetResult
      This API is called to get the result of the respective interrupt module.
    - 3.9.3.6 DIAG_INTERRUPT_Unregister
      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.
- 3.10 SW_SRAM_MARCH_TEST_01 - MarchB
  This module contains functional safety diagnostics API for SRAM March-B.
- 3.11 SW_SRAM_MARCH_TEST_01 - MarchC
  This module contains functional safety diagnostics APIs for SRAM March-C.
- 3.12 SW_SRAM_MARCH_TEST_01 - MarchC_Minus
