Figure 44. Clock Set Up Sequence (4)
<Example>
(1) After Power Up: PDN pin “L” Æ “H”
“L” time of 150ns or more is needed to reset the AK5700.
(2) DIF1-0 and FS1-0 bits should be set during this period.
(3) Power Up VCOM: PMVCM bit = “0” Æ “1”
VCOM should first be powered up before the other block operates.
(4) Normal operation starts after the MCKI, EXLRCK and EXBCLK are supplied.
