Figures 1.17.4 to 1.17.6 show the timer A-relatedregisters.Except in event counter mode, timers A0 through A4 all have the same function. Use the timer Ai moderegister (i = 0 to 4) bits 0 and 1 to choose the desired mode.Timer A has the four operation modes listed as follows:• Timer mode: The timer counts an internal count source.• Event counter mode: The timer counts pulses from an external source or a timer over flow.• One-shot timer mode: The timer stops counting when the count reaches “000016”.• Pulse width modulation (PWM) mode: The timer outputs pulses of a given width.f1f8f32fC32Clock sourceselectionPolarityselectionTAiIN(i = 0 to 4)• Timer• One shot• PWM• Timer(gate function)• Event counterClock selectionTB2 overflowExternalTAj overflowtrigger(j = i – 1.
