Hi Jiada

So how about this ? Code will be more simple/readable if ((id == 9) && (busif >= 4)) { adinr = SSI9_BUSIF_ADINR(); mode = SSI9_BUSIF_MODE(); daligh = SSI9_BUSIF_DALIGN(); } else { adinr = SSI_BUSIF_ADINR(); mode = SSI_BUSIF_MODE(); daligh = SSI_BUSIF_DALIGN(); } rsnd_mod_write(mod, adinr, rsnd_get_adinr_bit(mod, io) | chnl); rsnd_mod_write(mod, mode, rsnd_get_busif_shift(io, mod) | 1); rsnd_mod_write(mod, dalign, rsnd_get_dalign(mod, io));
