8/10-bit A/D Converter
The 8/10-bit A/D converter has functions for using RC sequential comparator conversion format to convert analog
input voltage into 10-bit or 8-bit digital values. The input signal is selected from 8-channel analog input pins, and
the conversion start can be selected from three types : by software, 16-bit reload timer 1 or a trigger input from
an external signal pin.
(1) 8/10-bit A/D converter functions
The A/D converter takes analog voltage signals (input voltage) input at analog input pins, and converts these to
digital values, providing the following features.
Minimum conversion time is 6.13
s (at machine clock frequency of 16 MHz, including sampling time) .
Minimum sampling time is 3.75
s (at machine clock 16 MHz)
The conversion method is an RC sequential conversion in comparison with a sample hold circuit.
Either 10-bit or 8-bit resolution can be selected.
The analog input pin can select from 8 channels by a program setting.
At completion of A/D conversion, an interrupt request can be generated, or EI2OS can be started.
Because the conversion data protection function operates in an interrupt enabled state, no data is lost even
in continuous conversion.
The conversion start source may be selected from : software, 16-bit reload timer 1 (rising edge) , or external
trigger input (falling edge) .
Three conversion modes are available
Conversion mode
Single conversion operation
Scan conversion operation
Single conversion mode
Converts the specified channel (1 channel
only) one time, then stops.
Converts multiple consecutive channels (up
to 8 channels may be specified) one time,
then stops.
Continuous conversion
mode
Converts the specified channel (1 channel
only) repeatedly.
Converts multiple consecutive channels (up
to 8 channels may be specified) repeatedly.
Stop conversion mode
Converts the specified channel (1 channel
only) one time, then pauses, waits until
the next start is applied.
Converts multiple consecutive channels (up
to 8 channels may be specified) , however
pauses after conversion of each channel,
waits until the next start is applied.
