The AK9844 has the power-down mode and the normal mode. When the PDEN instruction is executed while

the PD pin is high level, the AK9844 becomes the power-down mode. The AK9844 is in the power-down mode

until PDDS instruction is executed. After the PDDS instruction is executed, the AK9844 changed to normal

mode from power-down mode.

In case that the PD pin is low level, the PDEN/PDDS instructions are invalid and are not executed.
