Using all ADC channels, 18F4550

I've read the datasheet and didn't see any issues in using all 13 ADC channels at the same time, but are there any gotchyas out there I'm missing? I need to cycle through them all, read the values and check for the highest value and the lowest value and some stuff with that info.

Thanks.

I can't speak for an 18F4550 but I use 13 A/D channels with an 18F67k22 for monitoring by battery voltages and currents in my solar control system.

Make sure you "do" put a pause in between reads.... Either S/W or H/W for stabilisation

Just something that has caught me out in the past.
