pic configurations .

HI ALL ,
these lines were taken from awritten code which i want to burn into pi16f84a, but really i need to know the configurations for the code ( PWRT on or off ?)

; DEVICE PIC16F84A,HS_OSC,WDT_ON,PROTECT_OFF
processor 16F84A ; Use these
#include "p16f84a.inc" ; for 16F84A

; DEVICE PIC16C54,HS_OSC,WDT_ON,PROTECT_OFF
; processor 16C54 ; Use these
; #include "p16c5x.inc" ; for 16C54

__config H'3FF6'
; __config (_CP_OFF & _WDT_ON & _HS_OSC)
__idlocs H'0251' ;version 2.51
radix dec

thanX,
 

Re: pic configurations .

Hi,

in all my PIC projects I set PWRT on this gives a slight delay after reset (around 72 mS) but it makes sure that the oscillator has stabilized before enabling the processor.

best regards
 

Re: pic configurations .

It's a good idea to have PWRT on.
The WDT should be on only if you clear it periodically in the code.
