13.1 Timer A
Figure 13.3 Timer A Block Diagram
Figure 13.3 shows the Timer A Block Diagram. Figures 13.4 to 13.6 show the timer A-related registers.
The timer A supports the following four modes. Except in event counter mode, timers A0 to A4 all have the
same function. Use bits TMOD1 to TMOD0 in the TAiMR register (i = 0 to 4) to select the desired mode.
• Timer mode:
• Event counter mode:
• One-shot timer mode:
• Pulse width modulation (PWM) mode: The timer outputs pulses in a given width successively.

The timer counts an internal count source.
The timer counts pulses from an external device or overflows and
underflows of other timers.
The timer outputs a pulse only once before it reaches the minimum
count 0000h.
