Note 24. Data must not be written into addresses from “06H” to “1FH”.
Note 25. The bits indicated as “0” must contain a “0” value. When RSTN bit is set to “0”, the internal digital
filter and the control block are reset but the register values are not initialized.
Note 26. When the PDN pin is set to “L”, all registers are initialized to their default values.
