Re: I/O Pin status during startup
Hi, Tumbleweed
the funny thing is I had added the port setting lines right before the TRIS statements for a run With MPLAB 8.92 sim ...

With some "cleaning" ( wiped double definitions and "enlighted" the never-ending loop )
MPLAB 8.92 ( the last one ! ) is rather useful for those simple programs debugging using checking breakpoints as it is still working fine with W11 ...
************************************************** ***********************
Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...
************************************************** ***********************
IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!
