"No doubt you are aware that even though you set RB5 to an output, it powers
up as an input and doesnot change to an output until the point in your code
where you explicitly change it to an output."

Yeah, I am aware of that.

"My feeling on how this works (pure speculation here) is that once the ICD2
raises the /mclr line, it no longer matters what the lvp pin is doing. /mclr
is at Vpp and rules the roost until it is dropped."

The configuration word probably makes a difference as well. I found that if
I am using the ICD2 and the LVP is on, I could not program the part using
the ICD2.

"Of course, if you do enable lvp and don't set RB5 to an output then you may
encounter erratic behaviour after you finish programming - assuming your
circuit allows RB5 to go high."

If you enable it, you better be programming it using low voltage and that
pin cannot be used for anything.


Best regards,
Fred
