2.3.2.2 System March X
The system March X self test function is the essentially the same as the system March C module except that it only
implements the reduced March X algorithm. The module is designed to run after the application system has been
initialised and so should not be used to test the whole memory area in a single operation.
This test is configured to use 8 bit RAM accesses, and can allow a single byte to be tested. However, for all faults types
to be detected it is important to test a data range bigger than one byte.

Declaration
bool stl_RL78_march_c(uint16_t num, uint8_t *addr)
Description
This function tests the Ram memory using the March X algorithm over the address range supplied by the calling
function. The result status (Pass / Fail) is returned. This module is designed to be executed after the application
system has been initialised.
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
uint8_t *addr
Pointer to the start address of the RAM to be tested.
uint16_t num
The range (Number of bytes +1) of the RAM to be tested.
Output Parameters
NONE
N/A
Return Values
bool
Test status result is returned in CPU register A
0 = Test passed. 1 = Test or parameter check failed
