Does anybody know where the xtal port is in DEMOMC9S12XEP BOARD? As i know to use a PLL Clock, xtal port should be connected with appropriate capacitors and resistors but my board doesn't have. I've already checked schmetic, manual.
yes I meant that. So you mean I just need to make the right codes to use PLL, right? with no capacitors, any resistors.
i'm trying to do but still it is not working yet so i suspected that some components are needed to use that.
then can i ask one more thing? How much arrange of frequency can i use for bus clock? My friend said 50MHZ bus
clock changed by PLL is limit. i'm not sure he is right.
S12XE uses different PLL initialization code, so your old routines for S12XD most likely won't work.
Yes, S12XE bus clock tops at 50MHz. Check electrical specs in S12XE datasheet.
