through the last mile.There are other ways to get the best of you. For example, if you have the resources of a large company in your hands, you may be able to enter the market a step later than others, but you can still beat your competitors by using a huge market budget or on the basis of the company's existing distribution base. But the situation in the real world of VC after all is very few. Startups often don't win because they have huge resources-their success is often the result of an ins
Fin: Crystal Oscillator frequency
M: PLL0CFG [] N: PLL0CFG [] FCCO: PLL output frequency (Phase Lock output frequency) = Fin * 2 * M/N (this is not the case with the calculation formula of S3C2440, for more information, see datasheet)
CCLKSEL []: The frequency division value. Set the frequency division of the CCLK from the PLL0 output signal through the CCLKSEL + 1. CCLK: system clock = FCCO/(CCLKSEL + 1)
PCLKSEL []: Set the PWM1 peripheral clock frequency. All PCLKSEL are two-digit, PCLK =

A strange problem occurs: After iis7 is run, iis7 is opened on the taskbar, but the IIS control window cannot be displayed. (my operating system is MS Server 2008 R2). searching the Internet for half a day is fruitless. later, I found that the IIS window can be seen by logging on to the system with another account on the local machine ==> it should be something about some configuration files.
So we can see what files are accessed when running IIS, so we found the Free Software disk
wiring of ASICS. The clock available to the FPGA involves the problem of the global clock network. As this does not involve the problem of the artboard, for the clock network is not more than a repeat.
How to use the phase-locked loop: First locate and open the Megawizard plug-in Manager in the Tools menu bar and follow the steps below to configure the use of the PLL IP coreThis IP core outputs up to 5 signals, since we only need one output C0, so C1 ~ C4 is set to default (not turn
