*3: Please refer to "DAC etc" regarding CS "H" Hold Time before status mode execute.
*4: If READY/BUSY="H" is confirmed in status mode in the WRITE mode, the CS pin
can be changed to "L" shorter than the values specified on above.
Please refer to "DAC etc" regarding CS "H" Hold Time in case that AK9813B to be
connected in cascade is under programming cycle (READY/BUSY="L").
*5: 4.5V≤VCC≤5.5V
*6: 2.7V≤VCC<4.5V
