SDOS pin should be set to “L” when TDM= “1”.
“L”: 3-wire Serial, “H”: I
When this pin goes to “H”, soft mute cycle is initialized.
When returning to “L”, the output mute releases.
“L”: Normal Speed, “H”: Double Speed
“L”: mode 7 (disable) at parallel mode,
“H”: mode 0 (DZF1 is AND of all eight channels)
When “L”, the AK4529 is powered-down and the control registers are reset to default
state. If the state of P/S or CAD0-1 changes, then the AK4529 must be reset by PDN.
This pin should be connected to DVSS.
“L”: Internal ADC output, “H”: DAUX input
zero detect mode is selectable by DZFM3-0 bits at serial mode
