If there is a resistor from MCLR to VCC (4K7-20K) then YES.UnD3aD said:if mclr have Pull-up Resistor can i use this scheme to reset the pic?

You always need to add pull-up resistor to MCLR because PICs don't have internal pull-up on it. (Except when external MCLR is disabled, then the RESET input is held high by internal logic)Pommie said:UnD3aD said:if mclr have Pull-up Resistor can i use this scheme to reset the pic?
Yes, you could. Only problem is, as far as I am aware, the pics don't have a pull-up on MCLR.

That's only aplies when MCLR is disabled, and the PIN is used as GP port.UnD3aD said:12f683 have
from datasheet
"Master Clear w/internal pull-up"
Hmm that's a prety new feature... if you are correct, you won't need extra resistor.UnD3aD said:"A weak pull-up is automatically enabled
for GP3 when configured as MCLR and disabled when
GP3 is an I/O."
