In pulse period/pulse width measurement mode, the timer measures pulse period or pulse width of an
external signal. (See Table 15.11) Figure 15.22 shows the TBiMR register (i=0 to 5) in pulse period/pulse
width measurement mode. Figure 15.23 shows an operation example in pulse period measurement
mode. Figure 15.24 shows an operation example in the pulse width measurement mode.

The MR3 bit in the TBiMR register is set to "1" (overflow) simultaneously. When the
TBiS bit is set to "1" (start counting) and the next count source is counted after setting
the MR3 bit to "1" (overflow), the MR3 bit can be set to "0" (no overflow) by writing to
the TBiMR register.
