1. Interrupt request is not generated when the first effective edge is input after the timer started counting.
2. Value read from TBi register is indeterminate until the second valid edge is input after the timer starts counting.
3. The TB0S to TB2S bits are assigned to the bit 5 to bit 7 in the TABSR register.

In pulse period and pulse width measurement mode, the timer measures pulse period or pulse width of an
external signal (see Table 12.2.3.1). Figure 12.2.3.1 shows TBiMR register in pulse period and pulse
width measurement mode. Figure 12.2.3.2 shows the operation timing when measuring a pulse period.
Figure 12.2.3.3 shows the operation timing when measuring a pulse width.
