<R>
This is an application example where the width set to CR00n (4 clocks in this example) is to be output from the
TO0n pin when the count value has been captured & cleared.
The count value is captured to CR01n, a capture interrupt signal (INTTM01n) is generated, TM0n is cleared (to
0000H), and the TO0n output level is inverted when the valid edge of the TI00n pin is detected. When the count
value of TM0n is 0003H (four clocks have been counted), a compare match interrupt signal (INTTM00n) is
generated and the TO0n output level is inverted.
Remark n = 0:
Capture & count clear input
Compare match interrupt
