NOIOL1WAY fuse and configuration bits

[John5788]

I am still trying to track a problem down with setting peripheral pins on my PIC24HJ64GP504.

I saw 2 fuses that looked interesting, the IOL1WAY and NOIOL1WAY. I tried setting both of these fuses (exclusively) and noticed that the Peripheral Pin Select Configuration field is always Disabled.



Even if I uncheck the "Configuration bits set in code" box, and try to set the field manually, the field changes back to Disabled upon compilation.

I also tried taking all my code out, just the fuses and a blank main, but that configuration never changes to Enabled.

is this a bug?

Unchecking "auto-config" on compile and then fiddling the bits requires immediate program (and debugging if applicable).

The bits will always revert on recompile. That's normal.

As for the #fuse not setting it the way you think - report it to CCS. that may be a bug.

(also check the .LST file to see what it thinks is being set)

p.s. BTW, IOL1WAY being DISABLED (NOIOL1WAY) allows multiple settings of the PPS Pin Selects -- maybe not a bad thing for you unless your problem relates to locking them down as IOL1WAY (ENABLED) would do.

definitely a bug because I did a binary file compare of the two .hex files generated with both of the fuses, and there was no difference except in compilation date.
