Figure 1.14.14. Block diagram of timer B
Figure 1.14.15. Timer B-related registers (1)
Figure 1.14.14 shows the block diagram of timer B. Figures 1.14.15 and 1.14.16 show the timer B-related
registers.
Use the timer Bi mode register (i = 0 to 5) bits 0 and 1 to choose the desired mode.
Timer B has three operation modes listed as follows:
• Timer mode: The timer counts an internal count source.
• Event counter mode: The timer counts pulses from an external source or a timer overflow.
• Pulse period/pulse width measuring mode: The timer measures an external signal's pulse period or
pulse width.
