hi,i am using the keil c compiler, with an atmel at91m63200 simulator. my problem is,i want to define my own interrupt service routine , that must differ from the default one in the startup file, that branches to itself the whole time. how does the syntax look like for a an interrupt function?can anyone help me please? sorry for my english. thanks
Look up the interrupt keyword extension in the Manual http://www.keil.com/support/man/docs/c51/c51_le_interruptfuncs.htm "i want to define my own interrupt service routine , that must differ from the default one in the startup file" The startup file does nor define interrupt handlers - what do you mean?
