(CR000: compare register, CR010: capture register)
This is an application example where the TO00 output level is inverted when the count value has been captured &
cleared.
The count value is captured to CR010 and TM00 is cleared (to 0000H) when the valid edge of the TI000 pin is
detected. When the count value of TM00 is 0001H, a compare match interrupt signal (INTTM000) is generated, and
the TO00 output level is inverted.
