Notes:
For addresses from 0AH to 1FH, data must not be written.
When PDN pin goes “L”, the registers are initialized to their default values.
When RSTN bit goes “0”, the only internal timing is reset and the registers are not initialized to their default
values. All data can be written to the register even if PW or RSTN bit is “0”.
The “0” register should be written “0”, the “1” register should be written “1” data.
