Synopsis

CTL_STATUS_t ctl_memchk_march_a_test_8b(void *start,
                                        size_t byte_count);

Description

ctl_memchk_march_a_test_8b runs a MARCH A test over the memory pointed to by start of byte_count bytes.

The marching steps are:

↕(w0); ↑(r0,w1,w0,w1); ↑(r1,w0,w1);
↓(r1,w0,w1,w0); ↓(r0,w1,w0)

Return Value

ctl_memchk_march_a_test_8b returns a standard status code.
