Section 15 A/D Converter
15.5.3
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 15.5 shows the A/D conversion timing. Table 15.3 shows the A/D
conversion time.
As indicated in figure 15.5, the A/D conversion time (t
(t
conversion time therefore varies within the ranges indicated in table 15.3.
Specify the conversion time by setting bits CKS0 and CKS1 in ADCR with ADST cleared to 0.
Note that the specified conversion time should be longer than the value described in A/D
Conversion Characteristics in section 25, Electrical Characteristics.
In scan mode, the values given in table 15.3 apply to the first conversion time. The values given in
table 15.4 apply to the second and subsequent conversions.
