A-D Converter
Operation (1) Setting the A-D conversion start flag to “1” causes voltage input to the ANi pin to be output
Figure 2.7.11. Operation timing of one-shot mode, with external op-amp connection mode selected
2.7.5 Operation of A-D Converter (in one-shot mode, external op-amp connection mode selected)
In one-shot mode, choose functions from those listed in Table 2.7.5. Operations of the circled items are
described below. Figure 2.7.11 shows timing chart, and Figure 2.7.12 shows the set-up procedure.

from the ANEX0 pin. The A-D conversion is carried out on voltage input to the ANEX1 pin
(connect an operation amplifier between the ANEX0 pin and the ANEX1 pin).
