As requested by others, post your complete code and a schematic of your circuit.

Have you disabled analog features on any pins you use as digital?

HI ALL
THANKS for all
the program actually runs well, but the pause time is not correct and the current supply is not adequate ( due to dirty breadboar...)

at high frequency, some of the port pins is measured = 0, (when the port drives other ic) look like there is no power at all.
the set up is right:

_FOSC_INTIO67_1H
OSCTUNE = $40
OSCCON = $70

the PBADEN = OFF, so the portb is digital I/O
thanks a gain for all

regards
