[AK4452]
[2] DSD Mode
2ch Data is shifted in via the DSDL1 and DSDR1 pins using DCLK inputs. DSD data is supported by both
Normal mode (Figure 32) and Phase Modulation mode (Figure 33). Input data is clocked in on a rising or
falling edge of DCLK that is set by DCKB bit.
The frequency of DCLK is variable at 64fs, 128fs and 256fs by setting DSDSEL1-0 bits.
