9. With reference to the Timer & Interrupt Data Sheet for the Microchip 18F452 microcontroller : (see <[login to view URL]>) 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? ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
