Can u plese tell me the sequence of events occurs as soon as an interrupt occur in 8051. And also during RETURN How interrupts are handled is fully described in the document that Erik cited - look on Page 16, under the title, "How Interrupts Are Handled" (a bit cryptic, I know, but...). You should probably also download and study the rest of the so-called "bible" for the 8051: Chapter 1 - 80C51 Family Architecture: http://www.nxp.com/acrobat_d...ARCH_1.pdf Chapter 2 - 80C51 Family Programmer’s Guide and Instruction Set: http://www.nxp.com/acrobat_d...UIDE_1.pdf Chapter 3 - 80C51 Family Hardware Description: http://www.nxp.com/acrobat_d...WARE_1.pdf And don't forget the Tutorial on this vrey site: http://www.8052.com/tutorial.phtml |
