I am using a Basic ATOM Pro One-M in a design, and just found out I need one more I/O pin than available. I need something like a bank select line in a memory circuit (low speed, steady state most of the time). If I solder a small wire to one of the unused pins on the HD64F3694, would the compiler support it at the Basic language level, or would I need to operate it using assembly language and register manipulation?

For example, if I used the processor pin called "PB7/AN7" (currently not connected on the module), does it have an alias already (a "Pn" name), or is it completely unknown by the IDE when "BasicAtomPro ONE" is selected in the drop down list?

1. The compiler only knows the pins that are available.

2. If you hack it up like this you need to be carefull. There are secondary pins attached to the main pins for added functionality.

3. PB pins are input only pin.

4. If you modify it you know the drill as far as warranty goes.
