Write to both gain registers
Address byte bits:
• Bit 2 is read/write bit (1=read, 0=write).
• X is don’t care, recommended high for low
power.
Data byte bits:
• All registers get their default value 00Hex except
CR3 which gets FFHex during power-on reset.
• Default value for all bits is zero (00hex).
