4.4.2.1 DIAG_CPU_Registers
Software Requirement Reference ID : SW_CPU_REGISTER_TEST_01.
This API validates CPU Registers for Stuck Bits and Coupling Faults.
Description : The registers are tested in the following order:
- WREG
- TBLPTRL
- TBLPTRH
- TBLPTRU
- TABLAT
- PRODH
- PRODL
- FSR0L
- FSR0H
- FSR1L
- FSR1H
- FSR2L
- FSR2H
- RCON
- INTCON
- INTCON2
- INTCON3
- TOSU
- TOSH
- TOSL
- STKPTR
This test checks the integrity of the registers by testing for stuck at faults, insuring that the bits in the registers are not stuck at a value. The test can be done successively doing a write, read and check of 0x55 and 0xAA value into the CPU registers. The register is saved into RAM before the test is performed and restored after the test is done. Input : None
diag_cpu_registers_status_t DIAG_CPU_Registers(
void
)
Returns
| diag_cpu_registers_status_t | DIAG_CPU_REGISTERS_PASS, DIAG_CPU_REGISTERS_FAIL |
