The fault response message contains the same slave address as the command message, indicating to the master which slave is responding. The
function code of a fault response message is the logical OR of 80h and the original function code of 08h. This indicates to the master that the
message is a fault response message, instead of a normal response message.
The error code indicates where the error occurred in the command message. Refer to the section Error Codes, Table 2-14, for more information
on returned error codes.
