MCLR Enabled

When MCLR is enabled and the pin is held low, the device is held in Reset. The MCLR pin is connected to VDD through an internal weak pull-up.

The device has a noise filter in the MCLR Reset path. The filter will detect and ignore small pulses.

Important: An internal Reset event (RESET instruction, BOR, WWDT, POR, STKOVF, STKUNF) does not drive the MCLR pin low.
