16.4.3
The A/D converter has a built-in sample-and-hold circuit. The A/D converter samples the analog
input when the A/D conversion start delay time (t
starts conversion. Figure 16.2 shows the A/D conversion timing. Table 16.3 shows the A/D
conversion time.
As indicated in figure 16.2, the A/D conversion time (t
(t
conversion time therefore varies within the ranges indicated in table 16.3.
In scan mode, the values given in table 16.3 apply to the first conversion time. The values given in
table 16.4 apply to the second and subsequent conversions. In both cases, set bits CKS1 and CKS0
in ADCR to give an A/D conversion time within the range shown in table 21.7.
