 		 #108494 - Why is this wrong??
Responding to: ???'s previous message
Andy said:
The standard 8051 pins are not configurable

But read by yourself, what the "Bible" says about this issue:

"Because Port1, 2 and 3 have fixed internal pull-ups, they are sometimes called "quasi-bidirectional" port. When configured as inputs they pull high and will source current when externally pulled low."

"All the port latches in the 80C51 have 1s written to them by the reset function. If a 0 is subsequently written to a port latch, it can be reconfigured as an input by writing a 1 to it."

The "Bible" clearly states, that the port can be configured as input!
