C6748 PLL Issue

Hi, 

Can somebody please tell why the following PLL setting procedure doesn't work?

static void PLLsetting(void){
    sysRegs->KICK0R = 0x83e70b13;
    sysRegs->KICK1R = 0x95A4F1E0;											// Two values for unlocking SYSCFG registers.

    sysRegs->CFGCHIP0 = (sysRegs->CFGCHIP0) & !(1 << CSL_SYSCFG_CFGCHIP0_PLL_MASTER_LOCK_SHIFT);
    sysRegs->CFGCHIP3 = (sysRegs->CFGCHIP3) & !(1 << CSL_SYSCFG_CFGCHIP3_PLL1_MASTER_LOCK_SHIFT);
    																		// Unlocking the PPL registers for both PLL0 and PLL1
	////////////////////////////////////////PLL Setting//////////////////////////////////////////////
	pllRegs->PLLCTL = (pllRegs->PLLCTL) & !(1 << 8);						//Reference clock selection
	pllRegs->PLLCTL = (pllRegs->PLLCTL) & !(1 << 5);						//PLLENSRC bit activate PLLEN
	pllRegs->PLLCTL = (pllRegs->PLLCTL) & !(1<<9);							//External clock source selection to OSCIN
	pllRegs->PLLCTL = (pllRegs->PLLCTL) & !(1<<0);							//Bypassing the PLL by clearing PLLEN bit

	delay(100);

	pllRegs->PLLCTL = (pllRegs->PLLCTL) & !(1<<3);							//Reseting the PLL
	pllRegs->PLLCTL = (pllRegs->PLLCTL) & !(1<<1);							//Bringing the PLL out of power-down

	pllRegs->PREDIV = ((pllRegs->PREDIV) & (0xFFFFFFE0)) | (0x000000000);
	pllRegs->PLLM = ((pllRegs->PLLM) & (0xFFFFFFE0)) | (0x000000017);		//Loading the multiplier value. It is 11 here as the
																			//output of the PLL should be between 300 and 600 for this device.
	pllRegs->POSTDIV = ((pllRegs->POSTDIV) & (0xFFFFFFE0)) | (0x0000000C);	//Loading the post divider value.
	pllRegs->POSTDIV = (pllRegs->POSTDIV) | (1<<15);						        //Loading the post divider value. 

	pllRegs->PLLCTL = (pllRegs->PLLCTL) | (1<<3);							//Bringing the PLL out of reset
	delay(100);
	pllRegs->PLLCTL = (pllRegs->PLLCTL) | (1<<0);							//Bringing the PLL out of bypass

	sysRegs->CFGCHIP0 = (sysRegs->CFGCHIP0) | (1 << CSL_SYSCFG_CFGCHIP0_PLL_MASTER_LOCK_SHIFT);
	sysRegs->CFGCHIP3 = (sysRegs->CFGCHIP3) | (1 << CSL_SYSCFG_CFGCHIP3_PLL1_MASTER_LOCK_SHIFT);
	    																		// Locking the PPL registers

	sysRegs->KICK0R = 0x00000000;											//Locking the SYSCFG register
    sysRegs->KICK1R = 0x00000000;
}

I'm using LCDK6748 and running an LED blinking project on it, but the speed of the blinking doesn't change at all.

By the way, I am using AISgen for generating .bin file. Does it effect the PLL setting. I keep the 'Configure PLL0' check box disabled.

Any help would be appreciated.
