I'm currently designing a board using a Coldfire MCF52259.
I want to use the port PAN[7:0] as GPIOs, thus I won't deal with the ADC module at all.
My question is, can the pins VDDA, VSSA, VRH and VRL be left unconnected/not routed on the PCB ?
Or do I need to tight them to some potential like VCC/GND ?
Thank you !
