Can anyone tell me whether we can use the T0 pin / p3.4 pin of the AT89C55WD/8051 controller as general purpose output pin while the TIMER0 is used as internal timer?
I've not used that exact part, but you certainly can on the original 8051 and a number of derivatives.
The AT89C55WD is also a derivative of the standard 8051. Have you tried this in the standard 8051? If it works on the std 8051, it should also work on this part..
I said: "you certainly can on the original 8051 and a number of derivatives"
So, yes.
just do not set this bit 2 C/T -- Set to 1 by program to make timer 0 act as a counter by counting pulses from external input pin 3.4.
Thank you Mr.Erik. I am implementing it.
