29.5
The A/D converter generates an interrupt (ADI) at the end of A/D conversion.
The ADI interrupt request is enabled/disabled by specifying the ADIE bit in ADCSR. Either
interrupt generation or DMAC activation when A/D conversion ends can be selected by the
DMASL bit.
Since data for only one channel can be DMA transferred for each interrupt, data for all specified
channels can not be DMA transferred when more than one channel is specified in multi or scan
mode.
29.6
The A/D converter compares an input for an analog channel to its analog reference voltage and
converts it into 10-bit digital data. The absolute accuracy of this A/D conversion is the deviation
between the input analog value and the output digital value. It includes the following errors:
1. Offset error (figure 29.7 (1))
2. Full-scale error (figure 29.7 (2))
3. Quantization error (figure 29.7 (3))
4. Nonlinearity error (figure 29.7 (4))

Deviation between analog input voltage and ideal A/D conversion characteristics when the
digital output value changes from the minimum (zero voltage) B'0000000000 (B'000 in figure
29.7) to B'0000000001 (B'001 in figure 29.7)
Deviation between analog input voltage and ideal A/D conversion characteristics when the
digital output value changes from the B'1111111110 (B'110 in figure 29.7) to the maximum
B'1111111111 (B'111 in figure 29.7).
Intrinsic error of the A/D converter and is expressed as 1/2 LSB.
Deviation between analog input voltage and ideal A/D conversion characteristics between zero
voltage and full-scale voltage. Note that it does not include offset, full-scale, and quantization
errors.
