Notes: For addresses from 02H 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”.
