. Because there is no clock circuit inside the ADC0809, the required clock signal must be supplied by the outside world, usually using a frequency of 500KHZ

Note: The power supply voltage of k9f1208u0b is 3.3 V, the fclk of the system is 533 MHz, and the hclk is 533/4 = 133 MHz.
NAND Flash Controller Initialization
Call nf_init () in the mian function of stepldr to initialize the NAND flash controller. The following describes this function.
Where
// Hclk = 100 MHz
# Define tacls 7
# Define twrph0 7
# Define twrph1 7
(1) Configure nfconf in the configuration register of NAND Flash
The actual meanings of tacls, twrph0, and twrph1 can be found in th
manner. All these designs aim to enhance the adaptability to heterogeneity. It can be seen that the adaptability of telnet is heterogeneous to the application of the four Win2000 Telnet service.

analysis of this system, it is necessary to master the relationship between the connection of memory expansion circuit and the Operation Sequence of MCU external program memory, that is, the Data Bus D0 ~ of MCU ~ D7, address bus a0 ~ A15 and control signal, the signal connection between ale and extended EPROM, 74LS373, and the role of 74LS373 in the circuit.
In the figure, 74LS373 is an 8d latch with three-state output. It is grounded by three-state

You can point out the shader that needs to be compiled by #pragma only_renderers or #pragma exclude_ renderers directive This is primarily useful in this case, you are explicitly using some material language features on some platforms that you know are impossible on some platforms

development figures go away, is Microsoft really capable of maintaining the current glory of "my world? Continue users' enthusiasm for it? I am very skeptical. In addition, the commercial value of "my world" is almost exhausted. Not only are bestsellers, LEGO toys, and even related movies launched, which is almost the same as Rovio's "Angry Birds" series. A slight difference is that with the recent rise of Rovio, revenue, profit and user viscosity have shown signs of rapid decline, while "my wo

I believe many people know about Xbox. How is the Xbox game developed? Let's learn about this Xbox game development together.
First, prepare the development-related development tool xna3.0.
After xna3.0 is installed, it is automatically appended to the Project template of vs2008 development tool.

A large number of default applications are preinstalled in Windows 10 systems. Depending on the version you're using, you'll always see a lot of apps that you don't want to use in the Start menu, and you can actually uninstall any preinstalled applications you don't need with the system's own way. And all you have to do is simply look for an application in the Start menu and run as an administrator, and then copy the code below to complete it.
