3 XSP_RX_ XSP Rx channel n active phase. Valid only in 50/50 mode (XSP_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 XSP_RX_ XSP Rx channel n enable. Configures the state of the data for the XSP on channel n. The same rule applies to CHx_EN.
CHn_EN
0 Input channel data is not propagated to the internal data path
1 (Default) Input channel data is propagated to the internal data path
1:0 XSP_RX_ XSP Rx channel n size (in bits). Sets the output resolution of the XSP 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

DSD_ Digital volume control registers for DSD processor channel B. It allows independent control of the signal level in 1/2 dB
VOLUME_B increments from 0 dB. Volume settings are decoded as shown below. The volume changes are dictated by the DSD_
SZC bit. The same condition applies to DSD_VOLUME_A setting.
