 * @details The 8 blocks of memory of size 16 bytes are allocated
 * by k_calloc() API. When allocated using k_calloc() the memory buffers
 * have to be zeroed. Check is done, if the blocks are memset to 0 and
 * read/write is allowed. The test is then teared up by freeing all the
 * blocks allocated.
