3.2.3.1 DIAG_CPU_SelfTestSubset1()

diag_result_t DIAG_CPU_SelfTestSubset1 (void )

Software Requirement Reference ID: SW_CPU_SELF_TEST_LIB_01  

Executes the CPU self-test Subset 1.  

Functional items covered by Subset 1 are mentioned below:  

  • MOV and MOVW instructions are tested

  • Addressing modes tested: Immediate, File Register, Register Direct and Indirect (with Pre-Increment, Post-Increment, Pre-Decrement, Post-Decrement, Literal Offset and Register Offset)

  • All bits of the program memory address bus are toggled

  • All bits of the SRAM data memory address bus are toggled

  • All bits of the SRAM data bus are toggled

  • SWAP instruction is tested

  • All bit manipulation, bit test, compare and bit-compare-skip operations are tested

  • CPU registers tested for read/write operations

This API performs tests to verify the functionality of all the supported instructions mentioned above and updates the diag_result_t which contains the status for this diagnostic test.
Parameters:
None.
Returns:

DIAG_PASS  

DIAG_FAIL
