This is an application example where the width set to CR010 (4 clocks in this example) is to be output from the
TO00 pin when the count value has been captured & cleared.
TM00 is cleared (to 0000H) at the rising edge detection of the TI000 pin and captured to CR000 at the falling
edge detection of the TI000 pin. The TO00 output is inverted when TM00 is cleared (to 0000H) because the
rising edge of the TI000 pin has been detected or when the value of TM00 matches that of a compare register
(CR010).
When bit 1 (CRC001) of capture/compare control register 00 (CRC00) is 1, the count value of TM00 is captured
to CR000 in the phase reverse to that of the input signal of the TI000 pin, but the capture interrupt signal
(INTTM000) is not generated. However, the INTTM000 interrupt is generated when the valid edge of the TI010
pin is detected. Mask the INTTM000 signal when it is not used.
