3.2.2. 2/4/8/16-Channel Data Output(256 fs)

ADATA_REC supports up to 8 channel audio using single chip and up to 16 channel audio in

cascade mode. In this case, the bitrate of the audio signal should be 256 fs(RM_BITRATE,

0x07[5:4], BANK1). The number of output channel is configured by internal register value

(R_MULTCH, 0x08[1:0], BANK1) and the order of output channel is configured by internal

Therefore, the order of audio output can be changed.
