12f675 MCLR
#1 · October 14, 2025, 9:05 am
Hi again.. How is the MCLR handled in this micro? Even if i disable it in the config, the simulation still behave as if it was active, so a pullup resistor is needed, even if the datasheet of the micro says that when MCLR is disabled, it is internally pulled up, and the pin is available as input.
Attached an example to test.

Hi.
I think you should restart the simulation to get the new configuration.

I did it. Reloaded the hex too. In the info window i can see MCLR disabled, but if i dont put the pin at HIGH level, the program isn't executed

I can't reproduce, It is working for me:

My fault. I didn't check the CONFIG tab. I thought it was enough disable it in the hex config.
More than this, in the info window there was a clear message.....
