conversion time.
The A/D converter converts an analog input signal into a digital value, and consists of up to four channels (ANI0 to
The A/D converter has the following function.
Figure 9-1 shows the timing of sampling and A/D conversion, and Table 9-1 shows the sampling time and A/D
Note 2 or 3 clocks are required from the ADCS rising to sampling start.
10-bit resolution A/D conversion
10-bit resolution A/D conversion is carried out repeatedly for one channel selected from analog inputs ANI0 to
ANI3. Each time an A/D conversion operation ends, an interrupt request (INTAD) is generated.
