MDASM Features
•
Versatile 16-bit dual action unit allowing up to two events to occur before software intervention is
required
•
Six software selectable modes allowing the MDASM to perform pulse width and period
measurements, PWM generation, single input capture and output compare operations as well as
port functions
•
Software selection of one of the four possible 16-bit counter buses used for timing operations
•
Flag setting and possible interrupt generation after MDASM action completion
•
Software selection of output pulse polarity
•
Software selection of totem-pole or open-drain output
•
Software readable output signal status
