Is MCF5282 QAdC module works fine only for reference voltage of 5V ?.
I have connected analog supply of 3.3v to VDDA and VSSa and reference voltage levels are also connected to 3.3v(VRH) and 0v(VRL). it's not working. Result registers are not updating when the analog input is varying. Registers are updated either with 0 or 0x3FF. (Register value is 0 if the voltage is below 3.3 and 0x3FF for above 3.3. )
pls suggest me
