13. 8/10-bit A/D Converter
The 8/10-bit A/D converter converts analog voltage input to the analog input pins (input voltage) to digital values
(A/D conversion) and has the following features:
Minimum conversion time: minimum 15.0
s (at machine clock frequency of 16 MHz, including sampling time)
Minimum sampling period: 4
s/8 s (at machine clock frequency of 16 MHz)
Compare time: 99/176 machine cycles per channel
(99 machine cycles are used for a machine clock frequency below 10 MHz.)
Conversion method: RC successive approximation method with a sample and hold circuit
8/10-bit resolution
Analog input pins: Selectable from eight channels by software
Single conversion mode: Selects and converts one channel.
Scan conversion mode: Converts two or more successive channels. Up to eight channels can be programmed.
Continuous conversion mode: Repeatedly converts specified channels.
Stop conversion mode: Stops conversion after completing a conversion for one channel and wait for the
next activation (conversion can be started synchronously).
Interrupt requests can be generated and the extended intelligent I/O service (EI2OS) can be started after the
end of A/D conversion. Furthermore, A/D conversion result data can be transferred to the memory, enabling
efficient continuous processing.
When interrupts are enabled, there is no loss of data even in continuous operations because the conversion
data protection function is in effect.
Starting factors for conversion: Selectable from software activation, external trigger (falling edge) and timer
(rising edge).
