AT90PWM1
Amplifier 0 Control and Status register – AMP0CSR
Figure 19-17. 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.
Bit
Read/Write
Initial Value
• Bit 7 – AMP0EN: Amplifier 0 Enable Bit
Set this bit to enable the Amplifier 0.
Clear this bit to disable the Amplifier 0.
Clearing this bit while a conversion is running will take effect at the end of the conversion.
Warning: Always clear AMP0TS1:0 when clearing AMP0EN.
• Bit 6– AMP0IS: Amplifier 0 Input Shunt
Set this bit to short-circuit the Amplifier 0 input.
Clear this bit to normally use the Amplifier 0.
• Bit 5, 4– AMP0G1, 0: Amplifier 0 Gain Selection Bits
