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
