All blocks can be powered-down by setting the PDN pin to “L” regardless of register values setup. In this case, all
control register values are initilized.
When all power management bits are “0” in the 00H, 01H and 02H addresses, all blocks are powered-down. The
register values will remain unchanged. Power supply current is 18uA (typ) in this case. For fully shut down, The
PDN pin should be “L”.
