Thanks for the information.
One more question is that the range of the registers of 0x1A7 and 0x1A9 is 0 to -128dB with 0.5dB resolution.
I am confused with two different calculation about the above register.
For example, if the value of 0x1A7 is 0x0A,
Calculation 1)
10 * 0.5 - 128 = - 123 dB.
Calculation 2)
- (10* 0.5) = -5 dB
Which calculation is right?
