Figure 12.3 shows a block diagram of the timer A. Figures 12.4 to 12.6 show registers related to the timer A.
The timer A supports the following four modes. Except in event counter mode, timers A0 to A4 all have the
same function. Use the TMOD1 to TMOD0 bits in the TAiMR register (i = 0 to 4) to select the desired mode.

• Timer mode: The timer counts an internal count source.
• Event counter mode: The timer counts pulses from an external device or overflows and underflows of
• One-shot timer mode: The timer outputs a pulse only once before it reaches the minimum count “0000
• Pulse width modulation (PWM) mode: The timer outputs pulses in a given width successively.
