The A/D converter converts an analog input signal into a digital value, and consists of up to eight channels (ANI0 to
The A/D converter has the following function.
• 10-bit resolution A/D conversion
10-bit resolution A/D conversion is carried out repeatedly for one analog input channel selected from ANI0 to
ANI7. Each time an A/D conversion operation ends, an interrupt request (INTAD) is generated.
