Q1
2: Interrupt latency = 3.25Tcy, where Tcy = instruction cycle time.
3: CLKOUT is available only in RC oscillator mode.
4: The timer clock (after the synchronizer circuit) which increments the timer from FFh to 00h immediately sets the T0IF bit.
TMR0 TIMING: INTERNAL CLOCK/PRESCALE 1:2
TMR0 INTERRUPT TIMING
The TMR0 register will roll over 3 Tosc cycles later.
