    Turns out I don't really have a choice to stay with the 16F18877:

    - 16F1937 has TTL General Purpose pins.
    - 16F18877 has TTL and ST General Purpose pins.

    74HC14 only costs $0.09 at JLCPCB, but there's other costs associated with assembly, as well as lost real-estate on the PCB:

    My Creality Ender 3 S1 Plus is a giant paperweight that can't even be used as a boat anchor, cause I'd be fined for polluting our waterways with electronic devices.

    Not as dumb as yesterday, but stupider than tomorrow!

    You should be able to set the pin type in the 16F18877 to either ST or TTL to match the 1937 type if that's what you're after.
    I don't think your 'INLVLB = %00000100' statement changed anything for RB2... it's still the default setting.
