1.45 CLASSB_CPU_RegistersTest
Function
CLASSB_TEST_STATUS CLASSB_CPU_RegistersTest(bool running_context);
Summary
This self-test checks the processor core registers of the CPU, to detect stuck-at faults.
Description
This self-test writes test patterns into the processor core registers, and special function registers, and read them back to detect stuck-at faults. Special function register bits which are reserved or should not be modified during the test are not written.
Precondition
None.
Parameters
running_context - False for startup test. True for run-time test.
Returns
CLASSB_TEST_STATUS - Status of the test.
Example
CLASSB_TEST_STATUS classb_test_status = CLASSB_TEST_NOT_EXECUTED; // Perform run-time test of the CPU registers classb_test_status = CLASSB_CPU_RegistersTest(true);
Remarks
This self-test can be used during startup as well as run-time. If a failure is detected, this self-test remains in an infinite loop to avoid unsafe code execution.
