I am using a 12F683 and having no luck in disabling the MCLR pin (pin 4 bit 3) so that I can use it as an input.

In the PicBasic program, I put ANSEL = 0 to set all the pins to digital and CMCON0 = 7 to turn off the analog comparators.

In the hardware, I attached a 1K ohm pull-up resistor to pin 4, since I read that as an input, the internal pull-up is disabled.

In the meProg, configuration sections, I set Oscillator to INTOSCIO and th MCLR Pin Function to Input Pin

In the meProg, Option section, I checked both Update Configuration from File and Reread File Before Programming.

And yet, the MLCR pin 4 (bit 3) remains a Reset and not an Input.

What am I doing wrong or not doing to disable the MCLR function?

Thanks,

p.s. I also tried to program other 12F683 chips just in case the one I was using was bad, but they all worked the same way.
