This is an application example where the width set to CR000 (4 clocks in this example) is to be output from the
TO00 pin when the count value has been captured & cleared.
The count value is captured to CR010, a capture interrupt signal (INTTM010) is generated, TM00 is cleared (to
0000H), and the TO00 output is inverted when the valid edge of the TI000 pin is detected. When the count value
of TM00 is 0003H (four clocks have been counted), a compare match interrupt signal (INTTM000) is generated
and the TO00 output level is inverted.
