Memory Map and Registers
2.3.20 Gain Control 1 Register (ADC_GC1)
The gain control registers are used to control amplification of each of the 16 input
channels. GAIN0-GAIN7 control the amplification of inputs ANA0-ANA7 while
GAIN8-GAIN15 control the amplification of inputs ANB0-ANB7.
Address: ADC_GC1 – F080h base + 36h offset = F0B6h
