Generåte 2 wåves of dífferent duty cycle on 2 dífferent píns by usíng both tímer 8051

[Eshal]

Hello to all experts!

I want to generate two different waves on two different port pins of different duty cycle in 8051 using assembly language.

one wave is of 10 KHz of 50% duty cycle on pin p1.0
other wave is of 1 KHz of 10% duty cycle on pin p0.0

Here is the code what I get until now.

	org 0
		mov tmod, #12h          ;timer1 in mode=1 and timer0 in mode-2
		mov th0, #-50             ;reload value for timer0
		setb tr0                      ;start timer0
loop:         mov th1, #0feh
		mov tl1, #0ch
		setb tr1
wait:         jnb tf0, next                ;check if timer0 is overflowed
		clr tf0                         ;clear flag bit of timer0 is overflowed
		cpl p1.0
next:	        jnb tf1, wait                 ;chekc if timer1 is overflowed
		clr tr1                          ;stop timer1
		clr tf1                          ;clear flag bit of timer1 is overflowed
		cpl p0.0
		sjmp loop
		end

What changes should I make in order to satisfy above requirements? The above code shown is generating two different wave of 10KHz and 1KHz but both are 50% duty cycle. I want 10KHz as 50% and 1KHz as 10%.

Thank you very much
