13.2.3 Pulse Period and Pulse Width Measurement Mode
In pulse period and pulse width measurement mode, the timer measures pulse period or pulse width of an
external signal. Table 13.8 lists the Pulse Period and Pulse Width Measurement Mode Specifications.
Figure 13.20 shows Registers TB0MR to TB5MR in Pulse Period and Pulse Width Measurement mode.
Figure 13.21 shows the Operation Timing when Measuring Pulse Period. Figure 13.22 shows the Operation
Timing when Measuring Pulse Width.
