I am using MCF54415 custom built board with MQX and intend to use USB OTG on it.
However, I am facing USB clock setting issue. The problem is I cannot change OUTDIV4 bits in PLL Divider Register (PLL_DR).
I can see during dubug, in register PLL_DR the value is 0x00030460. But when I change it to 0x00070406, it remains the same even after execution of the PLL_DR = 0x00070406 command.
Any hints or suggestions are greatly appreciated.
Thank you for your time.
