A/D converter
operation
is reset (0) by software.
There is a delay time from when the A/D converter is enabled for operation until sampling is actually performed.
A/D conversion operations are performed continuously until bit 7 (ADCS0) of A/D converter mode register 0 (ADM0)
RESET input clears A/D conversion result register 0 (ADCR0) to 00H.
Confirm the conversion results by referring to the A/D conversion end interrupt request flag (ADIF0).
The sampling time of the A/D converter varies depending on the values set in A/D converter mode register 0 (ADM0).
For the sets in which a strict A/D conversion time is required, note the contents described in Table 14-2.
