16.5
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 enables ADI interrupt requests while the ADF bit in ADCSR is set to 1
after A/D conversion is completed.

• Absolute accuracy
The number of A/D converter digital output codes
The deviation inherent in the A/D converter, given by 1/2 LSB (see figure 16.5).
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 16.6).
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 16.6).
The error with respect to the ideal A/D conversion characteristics between the zero voltage and
the full-scale voltage. Does not include the offset error, full-scale error, or quantization error
(see figure 16.6).
The deviation between the digital value and the analog input value. Includes the offset error,
full-scale error, quantization error, and nonlinearity error.
