Bit 5 – Res: Reserved Bit
This bit is reserved in the ATmega103(L). Warning: When writing ADCSR, a logical “0”
must be written to this bit.
Bit 4 – ADIF: ADC Interrupt Flag
This bit is set (one) when an ADC conversion is complete and the result is written to the
ADC 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 corresponding 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 disabled. 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 XTAL frequency and the input
clock to the ADC.
ADC Data Register – ADCL
and ADCH
When an ADC conversion is complete, the result is found in these two registers. It is
essential that both registers are read and that ADCL is read before ADCH.
