12C671 - GP3 problem

[financecatalyst]

Hi, I am having problems with GP3 of my 12C671. I am trying to use it as an input along with others (GP0,1,2,...,4). MCLR is off. All are held high with 10K, but pressing GP3 low, does not result in PIC performing accordingly.
Any ideas please as how I can use this pin properly? Thanks

Does your config look something like this?

__config _INTRC_OSC_NOCLKOUT & _WDT_ON & _MCLRE_OFF & _CP_OFF

Does your config look something like this?

__config _INTRC_OSC_NOCLKOUT & _WDT_ON & _MCLRE_OFF & _CP_OFF

It is:
__config _INTRC_OSC_NOCLKOUT & _WDT_OFF & _PWRTE_ON & _MCLRE_OFF & _CP_ALL

Hi, Finance

could we see your config and declare stubb ???

better, whole PBP program if possible ?

Many, many reasons possible .... and crystal ball saturated.

DEFINE NO_CLRWDT
DEFINE OSC 4
Define OSCCAL_1K 1
@ __CONFIG _INTRC_OSC_NOCLKOUT & _WDT_OFF & _PWRTE_ON & _MCLRE_OFF & _CP_ALL
'// For PIC12C671
include "modedefs.bas"

'// Define variables

ToTx = 0

ADCON0.0=0
ADCON1=7

send:

goto send

re,

1) did you try a simple pin test ??? just to verify pin is still alive ???

2) did you verify your 10k is Ok ??? ( logic 1 on pin when nothing done )

Also, Did you try enabling the CLR Watchdog ??? ...

Do all '671 react like this ???
