Note) a 24.576 MHz clock is required for reset operation.
After application of clock, the /RESET pin should be pulled low. This power-on RESET is recommended whenever
power is applied or removed from the AK8851, until as applying voltage to the AK8851 cannot ensure proper device
initialization. Only a reset sequence can ensure this.
.
Output pins except for CLK27MO pin become low during the reset sequence.
