Note: For addresses 0BH, 0CH, 0EH and 0FH, data must not be written.
When the PDN goes to “L”, the registers are initialized to their default values.
When RSTN bit goes to “0”, the internal timing is reset and DZF1-2 pins go to “H”, but registers are not initialized
to their default values.
SMUTE and DFS0 bits are ORed with pins.
