[AK4458]
[2] DSD Mode
8ch Data is shifted in via the DSDL1-4 and DSDR1-4 pins using DCLK inputs. DSD data is supported by both
Normal mode (Figure 35) and Phase Modulation mode (Figure 36). 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.
