7. A/D Converter (Sequential comparison type)
(1) Overview
(2) Register List
• Control status register (ADCS)
• Data register (ADCR)
This A/D converter is a module that coverts analog input voltages to digital values, and provides the following
features.
• Minimum conversion time
• Built-in sample & hold circuit
• Resolution
• Analog input: 4 channels by program selection
• DMA transfer start from interrupt enabled
• Start sources can be selected from software, external trigger (falling edge), reload timer (rising edge).
Single conversion mode: Conversion on 1 select channel
Scan conversion mode: Select continuous multiple channels. Up to 4 channels can be selected by program.
Continuous conversion mode: Continuous conversion on selected channel
Stop conversion mode: 1-channel conversion then pause and wait until the next start is applied
