(1) Stop MCKI clock. BICK and LRCK are fixed to “H” or “L”.
Power down
Power supply current can be shut down (typ. 10
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. 10
μ
A) by stopping clocks and
setting PDN pin = “L”. When PDN pin = “L”, the registers are initialized.
