Your title says this:

pic16f877a CFGWORD2 not implemented

But your code says this:
Quote:
#include <16F887.h>

So which is it ? Those are two different PICs.

get rid of Proteus !!!
please read PIC101

this...
PIC16 model release 8.03.00 (Build 19892) simulating PIC1684 device. [U1]

appears to ONLY simulate 2 devices, neither is your device...
so I'll assume your version of Proteus is NOT capable of simulating the PIC you're trying to use, well test.

I changed #include <16F887.h> to #include <16F877a.h>

The problem now is I can't get 1us delay in Timer1.

Using this prescaler config
Code:
  setup_timer_1( T1_INTERNAL | T1_DIV_BY_2 );


What is wrong please ?

well I counted 5 or 6 lines where you disabled timer1( including inside the ISR) and nowhere you enable it after the first 'initialization' code..
the code seems correct
8MHz Fosc/4= 2 MHz then /2 give 1MHz which is 1us...

Yes now it work properly. The problem with Timer1 delay come from i miss to set pic frequency in proteus to 8 MHz, by default it is 1 MHz.
Thanks for your support.
