Timer A
2-12
Operation (1) Setting the count start flag to “1” causes the counter to perform a down count on the count

In timer mode, choose functions from those listed in Table 2.2.1. Operations of the circled items are
described below. Figure 2.2.6 shows the operation timing, and Figure 2.2.7 shows the set-up procedure.

(2) If an underflow occurs, the content of the reload register is reloaded, and the count continues.
(3) Setting the count start flag to “0” causes the counter to hold its value and to stop.
