3 ASP_RX_ ASP RX channel n active phase. Valid only in 50/50 mode (ASP_5050 = 1).
CHn_AP
0 (Default when n = 1) In 50/50 mode, channel data is input when LRCK/FSYNC is low
1 (Default when n = 2) In 50/50 mode, channel data is input when LRCK/FSYNC is high
2 ASP_RX_ ASP RX channel n enable. Configures the state of the data for the ASP on channel n. The same rule applies to CHx_EN.
CHn_EN
0 (Default) Input channel data is not propagated to the internal data path
1 Input channel data is propagated to the internal data path
1:0 ASP_RX_ ASP RX channel n size (in bits). Sets the output resolution of the ASP RX channel n samples.
CHn_RES _{00 8 bits per sample}
01 16 bits per sample
10 (Default) 24 bits per sample
11 32 bits per sample
