15.4.3
The A/D converter has a built-in sample-and-hold circuit. The A/D converter samples the analog
input at a time t
conversion timing. Table 15.4 indicates the A/D conversion time.
As indicated in figure 15.5, the A/D conversion time includes t
length of t
time therefore varies within the ranges indicated in table 15.4.
In scan mode, the values given in table 15.4 apply to the first conversion. In the second and
subsequent conversions the conversion time is fixed at 128 states when CKS = 0 or 66 states when
CKS = 1.
