A/D converter features are listed below.
10-bit resolution
Twelve input channels
Settable analog conversion voltage range
High-speed conversion
Choice of single mode or scan mode
Four data registers
Sample and hold function
Three kinds of conversion start
A/D conversion end interrupt generation
Module stop mode can be set
Conversion of analog voltages with the reference voltage pin (Vref) as the analog reference
voltage
Minimum conversion time: 13.3 µs per channel (at 20 MHz operation)
Single mode: Single-channel A/D conversion
Scan mode: Continuous A/D conversion on 1 to 4 channels
Conversion results are held in a 16-bit data register for each channel
Choice of software or timer conversion start trigger (TPU), or
A/D conversion end interrupt (ADI) request can be generated at the end of A/D conversion
As the initial setting, A/D converter operation is halted. Register access is enabled by
