<Example>
MCKI pin
PDN pin
(1) After Power Up: PDN pin “L”
(2) DIF1-0 and FS1-0 bits should be set during this period.
(3) Power Up VCOM: PMVCM bit = “0”
(4) Normal operation starts after the MCKI, EXLRCK and EXBCLK are supplied.
“L” time of 150ns or more is needed to reset the AK5701.
VCOM should first be powered up before the other block operates.
