The A/D converter consists of one 10-bit successive approximation A/D converter with a capacitive cou-
pling amplifier.
The result of an A/D conversion is stored into the A/D registers corresponding to selected pins. It is stored
into the AD00 register only when DMAC operating mode is entered.
Table 17.1 lists specifications of the A/D converter. Figure 17.1 shows a block diagram of the
A/D converter. Figures 17.2 to 17.6 show registers associated with the A/D converter.
