Timer B
Figure 1.48 shows the block diagram of timer B. Figures 1.49 and 1.50 show the timer B-related registers.
Use the timer Bi mode register (i = 0, 1) bits 0 and 1 to choose the desired mode.
Timer B has three operation modes listed as follows:
Timer mode
Event counter mode
Pulse period/pulse width measuring mode
: The timer counts an internal count source.
: The timer counts pulses from an external source or a timer overflow.
: The timer measures an external signal's pulse period or
pulse width.
