Hi Friends,
I Like to know how to write Interrupt using ASM (SYNTAX of Interrupt in ASM)...
The only specific requirement is that it uses RETI to return (not RET).
See also chapter 2 of the so-called "bible" for the 8051:
Chapter 2 - 80C51 Family Programmer's Guide and Instruction Set: www.nxp.com/.../80C51_FAM_PROG_GUIDE_1.pdf
The 8051 interrupt structure is described in Chapters 1 and 3:
