Note: For addresses from 0DH to 1FH, data is not written.
When 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, DFS0, SDOS and TDM0 are ORed with pins.
