2.3.3 Operation of Timer B (event counter mode)
In event counter mode, choose functions from those listed in Table 2.3.2. Operations of the circled items are
described below. Figure 2.3.6 shows the operation timing, and Figure 2.3.7 shows the set-up procedure.

Note: j = i – 1, but j = 2 when i = 0, j = 5 when i = 3
(1) Setting the count start flag to “1” causes the counter to count the falling edges of the count
(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.
