Input
Figure 43. Stop of Clock Sequence(3)
(2) Stop external clock
<Example>
(1) Pull down the XTI pin : MCKPD = “0” → “1”
When the external MCLK becomes Hi-Z or the external MCLK is input by AC couple, MCKI pin should be
pulled down.
(2) Stop an external MCLK
n Power down
Power down VCOM(PMVCM= “1” → “0”) after all blocks except VCOM are powered down and MCLK stops. The
AK4534 is also powered-down by PDN pin = “L”. When PDN pin = “L”, the registers are initialized.
