MB90620A Series
4. A/D Converter
The A/D converter converts the analog input voltage into a digital value. The features of this module are as follows:
Conversion time: Minimum of 7
s per channel (12 MHz machine clock)
RC-type successive approximation conversion method with sample and hold circuit
8-bit/10-bit resolution
Analog input is selectable by software from among 4 channels
A/D conversion mode selectable from the following three:
One-shot conversion mode: Converts a specified channel once.
Continuous conversion mode: Converts a specified channel repeatedly.
Stop conversion mode: Pauses after converting one channel and wait until the next activation (permits
synchronization of start of conversion).
Conversion mode:
Single-conversion mode: Converts one channel (when the start and stop channels are the same).
Scan conversion mode: Converts several consecutive channels (when the start and stop channels are
different).
When A/D conversion is completed, an “A/D conversion complete” interrupt request can be issued to the CPU.
Because generating this interrupt can be used to activate the I2OS and transfer the A/D conversion results to
memory, this function is suitable for continuous processing.
Activation sources can be selected from among software, an external trigger (falling edge), and timer (rising
edge).
