8.2.3 Timer Bi mode register

Figure 8.2.3 shows the structure of the timer Bi mode register. The operating mode select bits are used

to select the operating mode of timer Bi. Bits 2 to 7 have different functions according to the operating

mode. These bits are described in the paragraph of each operating mode.

8.2.2 Count start register

This register is used to start and stop counting. One bit of this register corresponds to one timer. (This is

the one-to-one relationship.) Figure 8.2.2 shows the structure of the count start register 0.
