Hi, I am beginning to program pic with pickit 2; I use micro code studio as compiler, (pbp). I have a problem with pic 18f4620.

I make this simple program, lampled, but the flashing of the led does not correspond with the program( 1 second on, 1 second off), synchronism lacks.

This is the program:
'************************************************* ***************

'************************************************* ***************

DEFINE OSC
TRISB = %00000000
PORTB = 0

START:
PORTB.1 = 1
PAUSE 1000
PORTB.1 = 0
PAUSE 1000
GOTO START
++++++++++++++++++++++++++++++++++++++++++++++++++ ++++++++

The problem is the configuration fuses?
