Table 1.14.8. Timer specifications in pulse period/pulse width measurement mode
Figure 1.14.19. Timer Bi mode register in pulse period/pulse width measurement mode
Note 1: An interrupt request is not generated when the first effective edge is input after the timer has started counting.
Note 2: The value read out from the timer Bi register is indeterminate until the second effective edge is input

Read from timer
Write to timer
In this mode, the timer measures the pulse period or pulse width of an external signal. (See Table 1.14.8.)
Figure 1.14.19 shows the timer Bi mode register in pulse period/pulse width measurement mode. Figure
1.14.20 shows the operation timing when measuring a pulse period. Figure 1.14.21 shows the operation
timing when measuring a pulse width.
