a) Which bit of T0CON turns the timer on?
b) What causes the TMR0IF bit of register INTCON get set to 1?
c) Assuming an oscillator frequency of 8MHz, what prescaler value should be used and what hexadecimal values must be loaded into the Timer0 low (TMR0L) and Timer0 high(TMR0H) to give a timer overflow after 200mS.
Show **ALL** your calculations
d) The values for TMR0L and TMR0H must be loaded into the timer in a particular order. In what order should they be loaded and why?
