■ Power Down
Power supply current can be shut down (typ. 50μA) by stopping clocks and setting PMVCM bit = “0” after all blocks
except for VCOM are powered down. It can also be shut down (typ. 0A) by stopping clocks and setting the PDN pin = “L”.
When the PDN pin = “L”, all registers are initialized.
