If I short two I/O pins of a PIC processor together and repeatedly reverse the states so that one is an input and the other an output and visa versa, will there be any contention?
I'm not sure which happens first when the state of the I/O is changed. If you reverse the state of 2 pins of the same port so that one is an input and the other an output, what happens first? Does the output become an input before the input becomes an output, or does it all happen at the same time?
Or, does it really matter since the possible contention time will be very short?
Thanks,
