Note 1: The weak pull-up resistor and associated current for the GP3/MCLR pin is non-linear when the respective

pin voltage is less than VDD - 1.0V. See parameter D061 for GP3/MCLR pin current specifications.

11.3 Reset

When MCLR is asserted, the state of the OSC1/CLKIN and OSC2 pins are as follows:
