10. 8/10 Bit A/D Converter
The 8/10 bit A/D converter has a function to convert analog input voltage to a 10 or 8-bit value using the RC
successive approximation conversion method.
8/10 Bit A/D Converter Functions
Below are the functions of the 8/10 bit A/D converter :
The minimum conversion time is 6.125
μ
s (with machine clock frequency of 16 MHz, including sampling time)
The minimum sampling time is 2
μ
s (with machine clock frequency of 16 MHz)
The RC successive approximation conversion method with sample-hold circuit is used for conversion
Resolution can be set to 10 or 8 bits
Input signal programmable from 8-channel analog input pins
When A/D conversion is completed, it is possible to output an interrupt request, and start EI
2
OS
In an interrupt-enabled state, when A/D conversion is executed, a conversion data protection function is
invoked
The conversion start factor can be set to software or 16-bit reload timer 1 output (rising edge)
The following 4 conversion modes are available :

The set channel performs conversion
once, then stops
Multiple linked channels (up to 16 channels can
be set) perform conversion once, then stop
Continuous Conversion
Mode
The set channel performs conversion
repeatedly
Multiple linked channels (up to 16 channels can
be set) perform conversion repeatedly
Stop Conversion
Mode
The set channel performs conversion
once, then pauses, and goes into
standby until started again
Multiple linked channels (up to 16 channels can
be set) perform conversion once, then pause,
and go into standby until started again
