INTRC_IO fuse is missing for 18F26J50 / 18F25J50 / 18F24J50

I get a compile error when trying to use INTRC_IO with a PIC18F26J50 / PIC18F25J50 / PIC18F24J50. The fuse is not recognized by the compiler.

In the PIC18F26J50 header file, "INTRC" appears twice. Unfortunately changing one of them to "INTRC_IO" doesn't work.

I'm using version 4.112 of the compiler.

Thanks,

The behaviour is coded in the device data base devices4.dat rather than header file. You can edit the fuse encoding with the CCS Device Editor tool, if you have the IDE version of the compiler.

Ultimately, you can set the complete binary device configuration data with a #rom statement, if the compiler doesn't manage it.

Generally, there are various complaints about arbitrary changes to device data, I don't understand why these things are happing again and again.
