In single sweep mode, choose functions from those listed in Table 2.7.7. Operations of the circled items
are described below. Figure 2.7.15 shows timing chart, and Figure 2.7.16 shows the set-up procedure.

Note: When
on voltage input to the AN
successive comparison register (conversion result) is transmitted to A-D register 0. The A-D
converter converts all analog input pins selected by the user. The conversion result is trans-
mitted to A-D register i corresponding to each pin, every time conversion on one pin is com-
pleted.
sion interrupt request bit goes to “1”. At this time, the A-D conversion start flag goes to “0”.
The A-D converter stops operating.
