When I put 5V continues supply i.e. system already gets +ve & -Ve 5V and does not depend on button press for -Ve. Then lowering GP3 does result in serout data.
In other words, pic gets its 5V continues and all pins pulled high with 10K. Lowering any pin results in serout data.

Are you applying 10V across the supply pins ? - I thought most pics will only work on 5V (ie +5v and 0V supply lines)Originally Posted by financecatalyst

No, it is 5V only. i.e. +5V & 0V.

We want the complete truth !!!
Hi, FC
Reading that , ... I think you didn't show or tell us everything :My circuit only gets power when any button is pressed.
OR the code shown only is a part of ...
OR you should show the Hardware side ...
no way for us to help further not knowing what you did and how you did it ...

Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!

Hi, I have attached the schematic and this is the complete code I have shown here. Hope to find a solution soon.

The way I read this, from the data sheet
Every time you press the GPIO.3 button the chip will go into a continuous reset.Most other registers are reset to a “reset
state” on Power-on Reset (POR), MCLR Reset, WDT
Reset, and MCLR Reset during SLEEP
The chip never gets to read the configuration to see that MCLR is turned off.

Comments:
1) - There are no smoothing capacitors either side of the regulator - what are you using to provide the 12v supply. If it's simply a bridge rectifier off a transformer then the supply will need smootthing.
2) - I assume the diodes are LEDS ? If so then you would be better off putting them in series with the resistors rather than in parallel.
3) - If they are not LEDS, then try removing them from the circuit, there may be some reverse bias or something causing the current to flow and possibly short out the supply ?
As Dave has mentioned - It does sound as if you are constantly resetting the chip before it configures itself.
