6.4.8 Pulse width measurement operation
restarting the timer in synchronization with the signal input to the TI000 pin.
(OVF00) of 16-bit timer mode control register 00 (TMC00). If it is set (to 1), clear it to 0 by software.

TM00 can be used to measure the pulse width of the signal input to the TI000 and TI010 pins.
Measurement can be accomplished by operating the 16-bit timer/event counter 00 in the free-running timer mode or by
When an interrupt is generated, read the value of the valid capture register and measure the pulse width. Check bit 0
