 		 #103027 - why enable UART interrupt??
Responding to: ???'s previous message
Erik Malund said:
MOV IE,#0A0H ;interrupt enable

IE.4 ES Enables or disables the Serial Port interrupt. If ES=0, the Serial Port interrupt is disabled.

So where do you expect the interrupt to come from?

Erik


I am only dealing with timer 2 interrupt at the moment so I don't see any point of enabling UART interrupt i.e. IE.4
even after your comments I did not see any harm in trying that and it did not work.

could anyone please try this program on their simulator and see it works ?
I would really appreciate your help guys
