When the clock mode is changed from EXT Master Mode to other modes, the register should be set as above table after
PDN pin = “L” to “H” or TE3-0 bits = “1010”.

MCKI pin
PDN pin
M/S bit
(1) After Power Up: PDN pin “L”
(2) DIF1-0, FS1-0, BCKO1-0, M/S, TE3-0 and TMASTER bits should be set during this period as follows.
(3) Power Up VCOM: PMVCM bit = “0”
(2a) M/S bit = “1”, setting of FS3-0 and BCKO1-0 bits.
(2b) Setting of DIF1-0 bits.
(2c) TE3-0 bits = “0101”
(2d) TMASTER bit = “1”: BCLK and LRCK start to output.
“L” time of 150ns or more is needed to reset the AK5700.
VCOM should first be powered up before the other block operates.
