19.6.4
The A/D converter has a built-in sample-and-hold circuit. The A/D converter samples the analog
input at a time t
shows the A/D conversion timing. Table 19.3 indicates the A/D conversion time.
As indicated in figure 19.8, the A/D conversion time includes t
length of t
time therefore varies within the ranges indicated in table 19.3.
In multi mode and scan mode, the values given in table 19.3 apply to the first conversion. In the
second and subsequent conversions the conversion time is fixed at 512 states when CKS = 0 or
256 states when CKS = 1.
