A/D Converter
XIV - 38 Operation
■ Setup Example of Multiple Channel A/D Converter Simultaneous Conversion Using PWM
as External trigger
A/D converter result can be obtained with feeding analog voltage by the ADIN00 and ADIN02 to activate A/D0
and A/D1 byPWM0 and by the ADIN01 and ADIN03 pins to activate A/D0 and A/D1 by PWM1. Conversion is
performed regularly PWM0 underflow.
