Getting problem while configuring PLL and using QSCI module

I am using MC56F82313vlc IC. I wanted to used QSCI0 module with a 9600 as its baud rate.Configure PLL to max frequency i.e OCCS_DIVBY = 0x2071 with default trimming factor i.e 0x220 and using ROSC8M as internal 8MHZ reference clock. I am not getting stable output frequency and also when I try to change trim frequency using SIM_NVMOPT2H i get default value only which is 0x222. So kindly help me to get a stable PLL output. If any one have sample code related to this IC please send me. So that I can get some idea to solve my problem.  
Thank you in Advance
