I am using TMS320F28335 controller. In that I have observed the following. 
    I want not to generate the XCLKOUT. For that I SET the CLKOFF bit in the XINTF registers in Initsyscntrl()----> InitPeripheralclocks(). 
    I write this code before the enabling of XINTF Clock. While i am running this code in RAM its working fine and XCLKOUT was not generated.
 
    If i dump this in flash and run from RAM by copying sections from FLASH to RAM its not working. 
    Its worked when I place the code after enabling of XINTF Clock and dump this in flash and run from RAM by copying sections from FLASH to RAM. Why this is              happened. Please clarify me.
Regards,
Swamy D.
