I have found a problem with the PIC18f46K40 datasheet or a problem in MCC - I am using the 44-pin TQFP package.

In the datasheet, the pin layout for the PIC18f46K40 is given below: enter image description here

The MCC (MPLABX IDE v4.15) pin layout is given below: enter image description here

The NC pins are not consistent. Which layout do I use in my design?

I have a strong feeling the MCC pin layout is right and the datasheet is incorrect for some reason.

    \$\begingroup\$ You're referring to an out-of-date (and incorrect) datasheet. The latest one is here, and appears to match what you're seeing in the MCC. \$\endgroup\$
