I'll very appreciate if you can help me with the following issue: Configured Timer 2 on P89C51RD2 . I'm getting around me and become confused from it ... So, I configure Timer 2 / 16-bit timer (the timer overflows (goes from 0xFFFF to 0x0000) An interrupt service routine (ISR) have to be invoked whan timer 2 have expired. (In which register I have to set the interrupt number void timer2_ISR (void) interrupt xx ??) Can you send me a 'C' example code which demonstrated this issue. Thanks Moshe
(In which register I have to set the interrupt number void timer2_ISR (void) interrupt xx ??) What do you mean by "In which register", just set the number at "xx" What the number is, tou find in the datasheet for your device. Erik
