Note 1) Writing into address 0x01 is enabled when writing into address 0x02 is performed. Be sure to write into address
0x01 first and then address 0x02.
Note 2) The initial register values are not defined. Therefore, even after [PDN1] is set to “High”, each bit value remains
undefined. In order to set all register values, it is required to write the data in all addresses of the register.
