21.10 Amplifier Control Registers
21.10.1
4317J–AVR–08/10
Amplifier 0 Control and Status register – AMP0CSR
The block diagram of the two amplifiers is shown on
Figure 21-18. Amplifiers block diagram
The configuration of the amplifiers are controlled via two dedicated registers AMP0CSR and
AMP1CSR. Then the start of conversion is done via the ADC control and status registers.
The conversion result is stored on ADCH and ADCL register which contain respectively the most
significant bits and the less significant bits.
