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?
Thank you Mr.Erik. I am implementing it.
Thank U Mr.Jack for your reply. I am implementing it in my software.
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.
I said: "you certainly can on the original 8051 and a number of derivatives"
So, yes.
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've not used that exact part, but you certainly can on the original 8051 and a number of derivatives.
