hi,
I'm using spc5633mmlq60, the max Fsys is 60mhz,according the datasheet.
Whe i set the Fsys 40Mhz,56Mhz,it work well.But when i set 60Mhz,i could not work.
Why the SPC5633mmlq60 Fsys could not be set 60Mhz?
MFD + 4
Fsys = Fref * ------------------------------
(PREDIV + 1) * 2e(RFD)
FMPLL setting: Fsys = 60Mhz,
(MFD=11,PREDIV=3,RFD=0,Fref=16Mhz)
Hi, this is incorrect setting. fVCO is out of range.
Use MFD = 11, PREDIF = 1, RFD = 1
Here my colleague shared great tool for MPC55xx and MPC56xx configuration. I believe it’ll help you:
