in actual code main program is not running into timer_isr,it is only part of codedo you think one can do such a silly mistake,not body tried to solve the problem which io had mentioned rather than pointing about code i am repeating again in real code main code is not jumping into isr_timer routine
org 0000h ljmp program_start ;bypass interupt table org 0003h ljmp interrupt0 org 0013h ljmp interrupt1 org 001bh ljmp isr_timer1 org 0030h program_start: mov PORT0,#0ffh mov PORT3,#0ffh mov PORT1,#0ffh mov PORT2,#0ffh mov TH1,#00h mov TL1,#00h mov TMOD,#11h mov IE,#10000001b setb TCON.0 setb TCON.2 here: sjmp here isr_timer1: reti interrupt0: setb PORT2.0 setb TCON.6 setb IE.2 reti interrupt1: clr PORT2.0 clr TCON.6 clr IE.2 reti |
