1. Bits CNT3 to CNT0 in the TCSPR register select no division (n = 0) or divide-by-2n (n = 1 to 15).
2. An interrupt request is not generated when the first valid edge is input after the count starts.
3. To set the MR3 bit to 0 (no overflow), wait for one or more count source cycles to write to the TBiMR register
4. A value read from the TBi register is undefined until the second valid edge is detected after the count starts.
In pulse period measurement mode and pulse width measurement mode, the timer measures pulse period or
pulse width of the external signal.
Table 15.11 shows specifications in pulse period measurement mode and pulse width measurement mode.
Figure 15.29 shows a pulse period measurement operation. Figure 15.30 shows a pulse width measurement
operation.

The TBiS bit (i = 0 to 5) in the TABSR or TBSR register is set to 1 (count starts)
The TBiS bit is set to 0 (count stops)
