L
time (1) of 150ns or more is needed to reset the AK4632.
(2) DIF1-0 and FS1-0 bits should be set during this period.
(3) Power Up VCOM: PMVCM bit =
0
1
VCOM should first be powered up before the other block operates.
(4) Release the pull-down resistor of the MCKI pin: MCKPD bit =
1
0
Power down PLL: PMPLL bit =
0
(5) Normal operation starts after the MCKI, FCK and BICK are supplied.
