  • 8259 VHDL代碼

    a8259 可編程中斷控制 altera提供 The a8259 is designed to simplify the implementation of the interrupt interface  in 8088 and 8086  based microcomputer systems. The device is known as a programmable interrupt controller.  The a8259 receives and prioritizes up to 8 interrupts,  and in the cascade mode, this can be expanded up to  64 interrupts. An asynchronous Reset and a clock input have been added to improve operation and reliability.

    his project was built and tested with WinAVR-20060125. Make sure the MCU target define in the Makefiles corresponds to the AVR you are using!! To build the code, just install WinAVR and run "make" from the console in echomaster and echoslave subdirs. "make program" will program the device if you have a AVRISP attached. Remember to set the AVR device to at least 8MHz. The AVR may use the programmable clock from MC1319x, just remember to check if the MC1319x and SPI communication is working FIRST! Otherwise you wont get any clock signal to the AVR and then you can t program it or Reset the fuses! The MC1319x has default clock output of 32kHz so you will have to set your programmer to a very low frequency (<=32kHz/4) to be able to program it while it is running on that!
