channel must be selected before entering Free Running mode. Selecting an active
channel after entering Free Running mode may result in undefined operation from the
ADC.
• Bit 4 – ADIF: ADC Interrupt Flag
This bit is set (one) when an ADC conversion completes and the Data Registers are
updated. The ADC Conversion Complete Interrupt is executed if the ADIE bit and the I-
bit in SREG are set (one). ADIF is cleared by hardware when executing the correspond-
ing interrupt handling vector. Alternatively, ADIF is cleared by writing a logical “1” to the
flag. Beware that if doing a read-modify-write on ADCSR, a pending interrupt can be dis-
abled. This also applies if the SBI and CBI instructions are used.
• Bit 3 – ADIE: ADC Interrupt Enable
When this bit is set (one) and the I-bit in SREG is set (one), the ADC Conversion Com-
plete Interrupt is activated.
• Bits 2..0 – ADPS2..ADPS0: ADC Prescaler Select Bits
These bits determine the division factor between the CK frequency and the input clock
to the ADC. See Table 21.
