 		 #102913 - Timer 2 in AT89S8252
Forum members

I am trying to use timer 2 of AT89S8252 to generate PWM, I have read the data sheet but could not get enough information, I was wondering if you guys can help,

what is Timer 2 Interrupt vector address?

If I want to specify Timer2 as in "auto-reload timer" mode, can I do it simply with this command

MOV T2CON,#00H

and then I can start/stop timer by controlling TR2.

how much role TMOD register has to play in initialising Time 2.

Any assistance would be much appreciated

regards
Kaz
