//  3) short_add: initialize by the application to filter the short_address,

//  4) group:     initialize by the application as address mask, it is the
//                "group_8_15,group_0_7" variable(s) defined in DALI Standard.
//                (In this 16-bit data, each bit = '1' enabled a group number,
//                bit-0 for group_0,  bit-1 for group_1, etc...)
//  5) code:      c.f. DALI command code definitions in "dali_code.h".
//  6) p_cc:      "Previous Command Code" used to verify the 2ND_CODE_NEEDED.
//  7) dtr:       DALI "Data Transfert Register" for data received or data to
//                send.
//  8) status:    Dali communication status
