I have decided to use DSC MC56F82743 in 32-pin LQFP package for my next project recently, but a small problem has appeared - I don't know where I should connect external crystal for this circuit? I cannot find suitable pins in datasheet..... I would like to avoid using internal oscillator.
Could somebody give me an advice to solve this problem, please?
Thank you a lot.

thank you a lot for your promt advice. I have usually used external crystal with other DSCs, but this circuit in such small package poses for me something new.
So, I will apply stand-alone sillicon oscillator.
Have a nice day!
Please use pin four for the oscillator module to connect to. No cyrstal can be used.
Please read reference manual (RM) section 18.
"18.2.4 External Clock Source - CLKIN - pin 4
In this mode, an external clock is applied using the external CLKIN pin function. This is
propagated into the OCCS and OCCS is configured to select CLKIN as the clock source."
