Hi ...
I m using the AT 89C4051 controller for my application and am facing a problem with PowerDown and Idle mode.
In a sample program that i have written for testing these modes .... what i have noticed is that the program goes to PowerDown and Idle mode by setting proper bits in the PCON register, however, after it is brought back to the normal mode (using hardware reset for PowerDown and hardware reset/software interrupt for Idle mode), the program starts executing from the very beginning .... and thisis not what i was expecting.
As per the manual, the program should have started executing from the statement next to the statement of changing to powerdown/Idle modes.
Pls help ...
Regards
