Syntax
bool stl_RL78_registertest_stack(void)
Description
Test the 16bit Stack Pointer (SP) register
The following tests are performed:
1. Write h'5555 to the register being tested.
2. Read back and check it is equal.
3. Write h'AAAA to the register being tested.
4. Read back and check that it is equal.
It is the calling function’s responsibility to ensure no interrupts occur during this test.
The original register content is restored on completion of the test
The function “indicate_test_result.c” will be called by the test harness control files (main.c) to process the test result
Note Function “indicate_test_result.c “is located in the module stl_main_example_support function.c
Input Parameters
