258.8051 microcontroller interrupts the process like?

In Electronic Infomation Category: 2 | on September 30,2011

The role of the external interrupt events asynchronously to make timely treatment. Process is divided into: interrupt request, the response in Sri Lanka, interrupt handling, interrupt return. When the CPU executes the main program when the first N instructions, CPU interrupt request signal and 258 datasheet and receiving the instructions in this section, after the implementation, interrupt the main program execution and 258 price and save the breakpoint address, and 258 suppliers and then turn to interrupt. CPU in each machine cycle, sequential sampling of each interrupt source, CPU cycle, the next in order of priority machine check interrupt, if the query to an interrupt flag to 1 when the next machine cycle, interrupt handling by priority , interrupt the system automatically by the hardware interrupt vector address is loaded into the co...
