<Example>
(1)
Power down PLL: PMPLL bit = “1”
“0”
Stop MCKO output: MCKO bit = “1”
“0”
(2)
Stop the external master clock.

(1) Stop the external clocks
Figure 49. Clock Stopping Sequence (4)
<Example>
(1)
Stop the external MCKI, BICK and LRCK clocks.
Power down
Power supply current can be shut down (typ. 1
μ
A) by stopping clocks and setting PMVCM bit = “0” after all blocks
except for VCOM are powered-down. Power supply current can be also shut down (typ. 1
μ
A) by stopping clocks and
setting PDN pin = “L”. When PDN pin = “L”, the registers are initialized.
