6.11.5. Audio Sample Packets
By setting audioif_cc[2:0] to a value greater then 2 (that is, 3 channel or more), the eight channel audio packet format will be used. The I2S can
be routed to different subpackets using the following fields:
•
subpkt0_l_src
•
subpkt0_r_src
•
subpkt1_l_src
•
subpkt1_r_src
•
subpkt2_l_src
•
subpkt2_r_src
•
subpkt3_l_src
•
subpkt3_r_src
The
audioif_ca[7:0] must be set to a speaker mapping that corresponds to the I2S input stream to subpacket routing. Using SPDIF has a default
setting of two channels.
