10. A/D Converter (Successive Approximation Type)
A/D Converter Features
The A/D converter converts analog input voltages to digital values.
• Peripheral clock (CLKP) 140 clock cycle
• Minimum conversion time 4.1 s/ch (for machine clock 34 MHz
• Built-in sample & hold circuit
• Resolution
• 4 channel program-selectable analog inputs
• Single, continuous, and stop conversion operation is supported.
• DMA transfer can be initiated by an interrupt.
• Selectable conversion activation trigger: Software, external trigger (falling edge), or reload timer (rising edge)
Single conversion mode : Convert 1 specified channel
Scan conversion mode : Continuous conversion of multiple channels. Conversion can be specified for up
Single conversion mode
Continuous conversion mode : Perform continuous conversion for the selected channel.
Stop conversion mode
10-bit
to 4 channels.
: Perform conversion for one channel, then wait for the next activation trigger
: Convert specified channel then stop.
(synchronizes the conversion start timing)
