RSTN: Internal timing reset
0: Reset. DZF pin goes to “H” and registers are not initialized.
1: Normal operation
When the states of DIF2-0,EXT,CKS2-0,DFS1-0 or FS1-0 changes, the AK4363 should be reset
by PDN pin or RSTN bit. Some click noise may occur at that timing.
DIF2-0: Audio data interface modes (See Table 4.)
Initial: “000”, Mode 0
EXT: Master clock select
0: PLL mode (27MHz clock input)
1: External clock mode. Internal VCO is powered down.
