I am new in BF processors. I want to use an external oscilator of 25MHz to CKLIN pin.I want to generate 600MHz for FVCO so 25MHzx24 = 600. But this value of 24 in Hex is 0x18. So in PLL_CTL register for MSEL i have to write this value , but bit 15 is reserved, so what is the value - 0x01800 or 0x18000? Because after that i want to generate 120MHZ for SCLK, and 300MHz for CCLK!!
