23.1

Overview of 10-bit A/D Converter

The 10-bit A/D converter is a 10-bit successive approximation type of 10-bit A/D
converter. It can be started via software, external trigger, and internal clock, with one
input signal selected from among multiple analog input pins.
A/D Conversion Functions
The A/D converter converts analog voltages (input voltages) input to an analog input pin to 10-bit digital
values.
• One of multiple analog input pins can be selected.
• The conversion speed is programmable to be configured (selected according to the operating voltage
and frequency).
• An interrupt is generated when A/D conversion completes.
• The completion of conversion can also be checked with the ADI bit in the ADC1 register.
To activate A/D conversion functions, follow one of the methods given below.
• Activation using the AD bit in the ADC1 register
• Continuous activation using the external pin (ADTG)
• Continuous activation using the 8/16-bit composite timer output TO00
