Most PIC's have a "weak pull up" for the MCLR pin. On the 16F913, I don't see this is an option in any register, however, on page 220 "Configuration Bits" [CONFIG1] there is a reference to MCLR. To tie it to VDD they say to enter "0" for this binary string. Wouldn't this mean that because you'd use a "0", if not entering CONFIG1 at all, it would automatically default to "0" and apply a weak-pull up on MCLR?

Otherwise, I would have to have a resistor/cap tied to MCLR which I really don't have the room to do if it's not absolutely necessary.
