14.4.3 Input Sampling and A/D Conversion Time
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 14-4 indicates the A/D conversion time.
As indicated in figure 14-5, the A/D conversion time includes t
length of t
time therefore varies within the ranges indicated in table 14-4.
In scan mode, the values given in table 14-4 apply to the first conversion. In the second and
subsequent conversions the conversion time is fixed at 256 states when CKS = 0 or 128 states
when CKS = 1.
