All API functions return API_OK if no error occurred. If the return value is not equal
to API_OK the function ApiGetErrorDescription can be used to obtain an error
description.
Note: ‘msg_cnt’, ‘err_cnt’, ‘lvw’ and ‘srvreq_cnt’ are cleared on restart of the AIM
board Bus Controller when the ApiCmdBCStart’ function is called.
