When the RSTN pin is driven to "L", all registers of AK8973 are initialized, resulting in power-down mode.
During sensor measurement mode, only MS1 register can be written in. Do not write in the registers other
than MS1.
TS1 is test mode setting addresses for testing before shipment. Do not use TS1. Otherwise, the operation
error may result.
