(1) 用单脉冲发生器的输出作为中断请求信号使8259A产生中断,进入中断后显示一个字符串。(2) 中断请求通过8259的IRQ2端输入,中断源可以是片外8253定时器输出的脉冲,并把8253的OUTO和总线槽IR02连接好。 (3) 编写程序,要求每次主机响应外部中断IRQ2时,显示字符串“THIS IS A 8259A INTERRUPT!”(或其它串),中断十次后,程序退出。

The IA-32 Software Developer’s Manual, Volume 3: System Programming Guide (Order Number 245472), is part of a three-volume set that describes the architecture and programming environment of all IA-32 Intel® Architecture processors. The IA-32 Software Developer’s Manual, Volume 3, describes the operating-system support environment of an IA-32 processor, including memory management, protection, task management, interrupt and exception handling, and system management mode. It also provides IA-32 processor compatibility information. This volume is aimed at operating- system and BIOS designers and programmers.

This will sample all 8 A/D-channels by the continous mode. Each end of conversion will call an interrupt routine, where the AD-channel is put to Port4[2..0] and the upper nibble of the result is put to Port4[7..4]. Port 4 is connected to the user LEDs of the FlashCan100P Evaluation-Board

This example provides a description of how to set a communication with the bxCAN in loopback mode: - transmit and receive a standard data frame by polling at 100Kbit/S - transmit and receive an extended data frame with interrupt at 500Kbit/S - lit some LEDs depending of the program succeed or not

This example provides a description of how to use a DMA channel to transfer a word data buffer from memory (Flash) to memory (RAM). The dedicated DMA channel is configured to transfer once a time a 32 word data buffer stored as constant in the Flash memory to another buffer in the RAM memory. The received data are stored in the DST_Buffer. The DMA channel transfer complete interrupt is enabled to generate an interrupt at the end of the buffer transfer. As soon as the transfer is completed an interrupt is generated and in the DMA channel interrupt routine the transfer complete interrupt pending bit is cleared. The data counter is stored before and after the transfer to show that all data has been transfered. TransferStatus gives the data transfer status where it is PASSED if transmitted and received data are the same otherwise it is FAILED
