Hi all,
Horrified with bascoms speed I have shifted to assembly
please let me know suppose I am getting some values in tl0, th0
I need to compare these values to some pre known values and give
outputs as per the range of freq.I am doing the following but
gives useless and erratic response.I have tested tl0,th0 hex
values with led's connected to ports they are correct.

do_action: clr c ;this is where action to be taken
clr psw.3
mov r6,tl0
mov r7,th0
mov a,#0fh
mov p1,a
mov a,#88h
subb a,r6
JC msb1
msb1:mov a,#13h
subb a,r7
JC action1
ajmp step1 ;perform action1

action1:mov a,#0Eh
mov p1,a
sjmp measure_again

step1: clr c
;clr psw.3
;mov r6,tl0
;mov r7,th0
mov a,#0fh
mov p1,a
mov a,#58h
subb a,r6
JC msb2
msb2:mov a,#1Bh
subb a,r7
JC action2
ajmp measure_again

action2:mov a,#0Dh
mov p1,a
ajmp measure_again
end

The problem here is only action2 gets performed and not action1 even
if the freq limit remains between 5khz to 7khz only 7khz step gets
performed or more correctly the very last step.please let me know if I am doing something wrong or is there some
other way to do this.



thanks
sanjeev
