I don't see why are needed here 1 and 2, the tmr0 always is rollowing
from 255 to 0 at every intcon_t0if events. Also clearing intcon_t0if have
nothing to do with t0ie or gie. You may use intcon_t0if without enabling
any interrupts in the main program.

        timer0_int
1       movlw 0
2       movwf TMR0
