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 18.5 shows the A/D conversion timing. Table 18.3 indicates
the A/D conversion time.
As indicated in figure 18.5, the A/D conversion time (t
