22.4.3
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
1, then starts A/D conversion. Figure 22.2 shows the A/D conversion timing. Table 22.4 indicates
the A/D conversion time.
As indicated in figure 22.2, the A/D conversion time (t
(t
time therefore varies within the ranges indicated in table 22.4.
In scan mode, the values shown in table 22.4 become those for the first conversion time. The
second and subsequent conversion times are listed in table 22.5. In either case, bits CKS1 and
CKS0 in ADCR should be set so that the conversion time is within the ranges indicated by the
A/D conversion characteristics.
