Figure 12.15 shows a block diagram of the timer B. Figures 12.16 and 12.17 show registers related to the
timer B.
Timer B supports the following four modes. Use bits TMOD1 and TMOD0 in the TBiMR register (i = 0 to 2)
to select the desired mode.

• Timer mode: The timer counts the internal count source.
• Event counter mode: The timer counts the external pulses or overflows and underflows of other timers.
• Pulse period/pulse width measurement mode: The timer measures the pulse period or pulse width of
• A/D trigger mode: The timer starts counting by one trigger until the count value becomes 0000
