“L”: 3-wire Serial, “H”: I
When returning to “L”, the output mute releases.
“L”: Normal Speed, “H”: Double Speed
state. If the state of P/S or CAD0-1 changes, then the AK4527B must be reset by PDN.
“L”: Internal ADC output, “H”: DAUX input
When this pin goes to “H”, soft mute cycle is initialized.
No internal bonding.
“L”: mode 7 (disable) at parallel mode,
“H”: mode 0 (DZF1 is AND of all six channels)
When “L”, the AK4527B is powered-down and the control registers are reset to default
This pin should be connected to DVSS.
No internal bonding.
“H”: Full-differential input, “L”: Single-ended input
zero detect mode is selectable by DZFM2-0 bits at serial mode
