plz tell me that is this program is correct or it needs some more addition or correction. all the details are written in front of every command after “;” sign
ORG 0013H ; INT1 ISR
clr TR0 ;stops timer 0(pin p3.3 will be connected with ECHO OUTPUT PULSE PIN of SRF04)
mov DPL,TL0 ;save the TL0 values to lower DPTR portion
mov DPH,TH0 ;save the TH0 values to upper DPTR portion
LJMP RANGE_CHECKER ;from here the DPTR value will be shifted to furhter part of this remaining programe
RANGE_CHECKER:
{{{{{{here i will write further program}}}}}}
ORG 0030H
MAIN:
setb tcon.3 ; make INT1 edge triggerd(high-to-low) interrupt
setb tcon.1 ;make INT0 edge triggerd(high-to-low) interrupt
mov Ie,#10000101b ;enable external INT0,ITN1
mov tmod,#10011001b ;make timr to strt/stop by EXTRNAL HARDWARE,MODE 1,16 bit timers
mov tl0,#0000 ;load initial values in timer TLO
mov th0,#0000 ;load initial values in timer THO
setb p1.0 ;make pin P1.0 HIGH
call delay ;this delay will HIGH pin P1.0 for 10 usec
delay:
l1:mov r0,#1
djnz r0,l1
nop
nop
clr p1.0
