Watchdog reset while changing CLock frequency

I have configured my stm32f427 microcontroller,  Sysclk to run in a clock frequency of 60mhz(HSI and PLL). I have reduced it to 16mhz (Sysclk directly from HSI). While executing this code watchdog resets.
Below mentioned the code I have used to change the clock frequency.
     RCC_HSICmd(ENABLE);
     while(RCC_GetFlagStatus(RCC_FLAG_HSIRDY) == RESET);


     RCC_HCLKConfig(RCC_SYSCLK_Div1); /* Configure HCLK same as SYSCLK */
     RCC_PCLK1Config(RCC_HCLK_Div2);
     RCC_PCLK2Config(RCC_HCLK_Div2);



Please help me in solving in this issue.

Thanks in Advance
