Description
This module tests the RL78 working registers and accumulators.
Registers AX, HL, DE, BC in all three register banks (Banks 0, 1, 2, 3)
These registers are tested as16bit registers.
The following tests are performed for each register:
1. Write h'5555 to the register being tested.
2. Read back and check they are equal.
3. Write h'AAAA to the register being tested.
4. Read back and check they are equal.
It is the calling function’s responsibility to ensure no interrupts occur during this test.
The original register contents are 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
NONE
N/A
Output Parameters
NONE
N/A
Return Values
bool
Test Result Status returned in CPU Register A
0 = Test passed. 1 = Test or parameter check failed
