Section 16 A/D Converter
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 includes t
length of t
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. In the second and
subsequent conversions, the conversion time is 128 states (fixed) when CKS = 0 and 66 states
(fixed) when CKS = 1.
