By default, the operating frequency of the S3C2410 CPU is 12 MHz. The PLL circuit can generate a higher clock speed for the CPU and peripheral devices. The S3C2410 has two PLL: mpll and upll, which are dedicated to upll and USB devices. Mpll is used for CPU and other peripheral devices. Mpll generates three clock frequencies: fclk, hclk, and Plck. Fclk is used for CPU cores, hclk is used for AHB Bus devic
