15.5
The A/D converter generates an A/D conversion end interrupt (ADI) at the end of A/D conversion.
Setting the ADIE bit to 1 when the ADF bit in ADCSR is set to 1 after A/D conversion is
completed enables ADI interrupt requests. The data transfer controller (DTC) can be activated by
an ADI interrupt. Having the converted data read by the DTC in response to an ADI interrupt
enables continuous conversion to be achieved without imposing a load on software.

Name
ADI0
The number of A/D converter digital output codes.
The deviation inherent in the A/D converter, given by 1/2 LSB (see figure 15.6).
The deviation of the analog input voltage value from the ideal A/D conversion characteristic
when the digital output changes from the minimum voltage value B'0000000000 (H'000) to
B'0000000001 (H'001) (see figure 15.7).
The deviation of the analog input voltage value from the ideal A/D conversion characteristic
when the digital output changes from B'1111111110 (H'3FE) to B'1111111111 (H'3FF) (see
figure 15.7).
The error with respect to the ideal A/D conversion characteristic between the zero voltage and
the full-scale voltage. Does not include the offset error, full-scale error, or quantization error
(see figure 15.7).
The deviation between the digital value and the analog input value. Includes the offset error,
full-scale error, quantization error, and nonlinearity error.
