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

Hi, Shreeram,

Regarding your question, I think you can develop the code based on PE, the PE can generate the code to use internal 8MHz clock and use PLL to multiply the clock to 60MHz.

Hope it can help you
