Section 18 A/D Converter
18.4.3
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 18.2 shows the A/D conversion timing. Table 18.3 shows the A/D
conversion time.
As indicated in figure 18.2, the A/D conversion time includes t
length of t
time therefore varies within the ranges indicated in table 18.3.
In scan mode, the values given in table 18.3 apply to the first conversion time. In the second and
subsequent conversions, the conversion time is 128 states (fixed) when CKS = 0 and 66 states
(fixed) when CKS = 1.
