Functions with more than eight control bits, such as PLL divide ratio, gain, and offset, are only updated when the LSBs are written to (for example, Register 0x02 for
PLL divide ratio).
Gain registers (Register 0x05, Register 0x07 and Register 0x09) when written to must each be followed with a write to their next register: Register 0x05 and Register
0x06, Register 0x07 and Register 0x08, and Register 0x09 and Register 0x0A.
