3. When conversion of all the selected channels is completed, the ADF bit in ADCSR is set to 1.
4. The ADST bit is not cleared automatically, and steps [2] to [3] are repeated as long as the

The A/D converter has a built-in sample-and-hold circuit. The A/D converter samples the analog
input when A/D conversion start delay time (t
conversion. Figure 17.2 shows the A/D conversion timing. Table 17.3 indicates the A/D
conversion time.
As indicated in figure 17.2, the A/D conversion time (t
time (t
total conversion time therefore varies within the ranges indicated in tables 17.3.
In scan mode, the values given in tables 17.3 apply to the first conversion time. The values given
in tables 17.4 apply to the second and subsequent conversions.
If the ADIE bit is set to 1 at this time, an ADI interrupt is requested. Conversion of the first
channel in the group starts again.
ADST bit remains set to 1. When the ADST bit is cleared to 0, A/D conversion stops and the
A/D converter enters wait state. If the ADST bit is later set to 1, A/D conversion starts again
from the first channel in the group.
