Syntax
bool stl_RL78_registertest_es(void)
Description
Test the 8bit data extension (ES) register
The following tests are performed:
1. Write h'05 to the register being tested.
2. Read back and check it is equal.
3. Write h'0A to the register being tested.
4. Read back and check that it is equal.
Please note that the top 4 bit are fixed to “0”
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
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
