 *      - ERR is the error code. (defined by EC_RES_ constants)
 *      - Px is the optional payload.

 *        (defined by ec_params_ and ec_response_ structures)
 *      - S is the checksum which is the sum of all payload bytes.
 *
 * On LPC, CMD and ERR are sent/received at EC_LPC_ADDR_KERNEL|USER_CMD
