(10) A/D converter sampling time and A/D conversion start delay time
The A/D converter sampling time differs depending on the set value of the ADM register. A delay time exists
until actual sampling is started after A/D converter operation is enabled.
When using a set in which the A/D conversion time must be strictly observed, care is required for the contents
shown in Figure 13-10 and Table 13-4.
