DMRE:
DSD mute release
0: Hold (default)
1: Release Mute
This register is only valid when DDM bit = “1” and DMC bit = “1”. When the AK4495S/95
mutes DSD data by DDM and DMC bits settings, the mute is released by setting DMRE bit to
“1”.
DMC: DSD mute control
0: Auto Return (default)
1: Mute Hold (manual return)
This register is only valid when DDM bit = “1”. It selects the mute releasing mode of when the
DSD data level becomes under full-scale after the AK4495S/95 mutes DSD data by DDM bit
setting.
DDM: DSD data mute
0: Disable (default)
1: Enable
The AK4495S/95 has an internal mute function that mutes the output when DSD audio data
becomes all “1” or all “0” for 2048sample (1/fs). DDM bit controls this function.
