Section 38 A/D Converter
38.7.3
Four types of frequency divided clocks can be used as the clock for A/D conversion.
Since the internal circuit configuration affects the limits of the interface between the analog and
digital sections, be sure to see table 38.6 when setting the Pck0 clock and clock division ratio.
Table 38.6 Relationship between Clock Division Ratio and Usable Pck0 Clock Frequency
38.7.4
In multi mode or scan mode, A/D conversion does not stop as soon as the setting to halt A/D
conversion has been made. A/D conversion stops as soon as A/D conversion of the data in the
relevant channel has finished.
