ADC Control and Status Register B
• Bit 4 – ADIF: ADC Interrupt Flag
This bit is set when an ADC conversion completes and the data registers are updated. The ADC
Conversion Complete Interrupt is requested if the ADIE bit is set. ADIF is cleared by hardware
when executing the corresponding interrupt handling vector. Alternatively, ADIF is cleared by
writing a logical one to the flag.
• Bit 3 – ADIE: ADC Interrupt Enable
When this bit is written to one, the ADC Conversion Complete Interrupt request is enabled.
• Bits 2:0 – ADPS2:0: ADC Prescaler Select Bits
These bits determine the division factor between the system clock frequency and the input clock
to the ADC.
Table 13-3.
• Bits 7:3 – Res: Reserved Bits
These bits are reserved and will always read zero.
• Bits 2:0 – ADTS2:0: ADC Auto Trigger Source
If ADATE in ADCSRA is written to one, the value of these bits selects which source will trigger
an ADC conversion. If ADATE is cleared, the ADTS2:0 settings will have no effect. A conversion
will be triggered by the rising edge of the selected Interrupt Flag. Note that switching from a trig-
ger source that is cleared to a trigger source that is set, will generate a positive edge on the
