I'm using the SCI3 on a MCF51CN128 processor. It's connected to a CP2102 chip to convert from UART to USB signals. I have my board connected to a PC running HyperTerminal and am trying to talk to the unit. It's working well in most situations.
However, it will occasionally get into a state where the Vsci3rx interrupt is being triggered repeatedly by a single keypress. The interrupt continues indefinitly.
What kinds of things should I look for and double-check?
