Claus Knudsen said:

;Code in the 8051 book i'm reading:

ORG 0

LJMP MAIN

ORG 0BH ;or other interrupt address
LJMP timer1_ISR

ORG 23H ;serial interrupt for example
LJMP serial_ISR

ORG 30H
MAIN:
; initialize
; initialize ports, timers, variables etc
.
.
.

; do forever
do_forever:
; do what you have to do between interrupts
.
.
.

jmp do_forever


ORG 100H;
timer1_ISR:
.
.
RETI

serial_ISR:
;.
;.
RETI

end



can any one tell me where org 100h & org 30h branches in the above code..
