I want to use the MCLR enable pin on the PIC16F15355 as input pin (Port E pin 3).
I set the appropriate config bit in the Build|Project Options.
But depending on the signal at that pin, the controller still resets unexpectedly.
Is there anything else I need to do to disable the MCLR and enable the input?

Whooa! This has been resolved. There is a config bit for LVP (Low Voltage Programming), and if this is enabled, it overrides the setting for MCLR/E3 input. Set LVP to disable, set MCLR to '.. is input pin' and all works as intended.

Hi Jan, Glad you got it working and thanks for letting us know.

For me LVP is a setting to always avoid if you can, it can essentially put the running chip into none running program mode if left floating and worst case has the potental to erase/reprogram the device given the correct sequence of inputs or noise on the programming pins.
