Power-on reset. Start-up timer.

[Lasse1]

Hello.
I have a pic16f690 in a project. It works fine at the developement board. But mounted at the card i like to use it with, the program will not start. (It starts if I push the MCLR-pin) Probably this problem is caused by a slow power-up, i have a condensator connected to pwr.
I read in the data cheet that this pic have a couple of featuers who maybee can solve my problem. Power-on-reset, power-up-timer and maybee others. But how do I program it into the pic??
I found this string in this forum: "_PWRT_ON_2L" but I can not find any other code ty try. (It didn´t help).
Can anyone help me?

The MCLR pin needs to be pulled high or shut off.
If you shut it off it can be used as an INPUT.

Add this to your configuration to turn it off

_MCLRE_OFF

And this is a helpful thread

Hi again.
Thank you for your fast answer. It was a helpful link you gave me, I learned a little bit moore. I tried booth "POR" and "PWRT" but unfortunal it didn´t solve the problem. Do you have some other idea? Otherwhise I have to try to solve it the hardwhere-way.
Friendly regards / Lasse

Did you try
_MCLRE_OFF

[Lasse1]

Yes. I did.
And to be clear I can say that I am complete sure that my problem depend on power-up. (If I set the PIC in the holder with the pwr-leg bended away, and then connect it after the unit is powered-up, the pic starts correct)
You don´t have any other idea?
Friendly regards / Lasse

I am not sure what you mean by pwr-leg?
Can you post how everything is connected using pin numbers in the description or a schematic?
