C
Figure 15.3 shows a block diagram of the timer A. Figures 15.4 to 15.7 show registers associated with the
timer A.
The timer A supports the following four modes. Except in event counter mode, all timers A0 to A4 have the
same function. The TMOD1 and TMOD0 bits in the TAiMR register (i=0 to 4) determine which mode is
used.
Table 15.1 lists TAi
when used as an input.

• Timer mode: The timer counts an internal count source.
• Event counter mode: The timer counts an external pulse or an overflow and underflow of other timers.
• One-shot timer mode: The timer outputs one valid pulse until a counter value reaches "0000
• Pulse width modulation mode: The timer continuously outputs desired pulse widths.
