*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 AK9813 to be connected in cascade
is under programming cycle(READY/BUSY="L").
