(j = i - 1. Note, however, that j = 4 when i = 0)
Timer A
Except in event counter mode, Timers A0 through A4 all have the same function. Use the Timer Ai mode register (i = 0 to
4) bits 0 and 1 to choose the desired mode.
Timer A has 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 "0000
• Pulse width modulation (PWM) mode: The timer outputs pulses of a given width.
Figure 1.76 and Figure 1.77 show block diagrams of Timer A. Figure 1.78 to Figure 1.80 show the Timer A-related
registers.
