mcf52259 ADC question

I noticed in the datasheet that pins 22/23 are 'SYNC A' and 'SYNC B' which are supposedly to be triggered when an ADC measurement/conversion is wanted to be made. My question is are these pins REQUIRED to be triggered in order for an ADC to take a measurement and make a conversion?


Currently, we are able to take measurements WITHOUT triggering these pins, but I just want to make sure were not doing this 'by chance' and eventually have future problems and not be able to utilize these ADC channels due to us not using the SYNC A and SYNC B pins.




Thanks for any insight!
