(3) How the trigger conversion function operates
After setting up the A/D conversion enabled channels and other settings, turning on and off Initial data setting
request flag (RY9) results in the module entering the waiting for trigger input state.
Turning on Trigger conversion request (RY19, RY29) from off enables A/D conversion in all the channels where
A/D conversion is enabled.
Ex.
Operation until Trigger conversion completed flag (RX19) turns on from off after turning on Trigger
