8/10-Bit A/D Converter
Overview of the 8/10-bit A/D converter
The 8/10-bit A/D converter uses RC successive approximation to convert analog input voltages to an 8-bit or
10-bit digital value.
The input signals can be selected from the eight analog input pin channels.

time) .
The minimum sampling time is 2.0

s (for a 16 MHz machine clock)
Conversion method RC successive approximation with sample & hold circuit
Resolution
8-bit or 10-bit, selectable
Analog input pins
Eight analog input pin channels are available. The input pin can be selected by the program.
Interrupts
An interrupt request can be generated and EI

OS invoked when A/D conversion completes.
The conversion data protection function operates when A/D conversion is performed with
the interrupt enabled.
A/D conversion
start trigger
The conversion start trigger can be set from the following options : software, output of 16-
bit reload timer 1 (rising edge) , or zero detection edge from 16-bit freerun timer.

OS support
Supported by the extended intelligent I/O service (EI

OS) .
Single Conversion Mode Operation
Scan Conversion Mode Operation
Single-shot conversion mode 1
Single-shot conversion mode 2
Performs one conversion for the spec-
ified channel (1 channel) then halts.
Sequentially performs one conversion
for multiple channels (up to 8 channels
can be set) , then halts.
Continuous conversion mode
Performs repeated conversions for the
specified channel (1 channel) .
Performs repeated conversions for the
specified channels (up to 8 channels
can be set) .
Incremental conversion mode
Performs one conversion for the spec-
ified channel (1 channel) then halts
and waits for the next activation.
Sequentially performs one conversion
for multiple channels (up to 8 channels
can be set) , then halts and waits for
the next activation.
