<Example>
MCKO bit
MCKI pin
PDN pin
(1) After Power Up: PDN pin “L”
(2) DIF1-0, PLL3-0, FS3-0, BCKO1-0 and M/S bits should be set during this period.
(3) Power Up VCOM: PMVCM bit = “0”
(4) Enable MCKO output: MCKO bit = “1”
(5) PLL starts after that the PMPLL bit changes from “0” to “1” and PLL reference clock (MCKI pin) is supplied.
(6) The normal clock is output from MCKO after PLL is locked.
(7) The invalid frequency is output from MCKO during this period.
(8) EXBCLK and EXLRCK clocks should be synchronized with MCKO clock.
“L” time of 150ns or more is needed to reset the AK5701.
VCOM should first be powered up before the other block operates.
PLL lock time is 40ms(max) at MCKI=12MHz
