Here is the link of CY91520 sample code but the PLL is configured in startup.asm in assembler:
//Select tab "Sample Program"
If you need to configure PLL in C code, please kindly refer to the start.asm and chapter 5 of CY91520.
Thank you for your reply. You are right. I done something similiar.
What I did:
Here I copy pased pll init rountine from asm file
And it works perfect:)
