This is an application example where the width set to CR01n (4 clocks in this example) is to be output from the
TO0n pin when the count value has been captured & cleared.
TM0n is cleared (to 0000H) at the rising edge detection of the TI00n pin and captured to CR00n at the falling
edge detection of the TI00n pin. The TO0n output level is inverted when TM0n is cleared (to 0000H) because the
rising edge of the TI00n pin has been detected or when the value of TM0n matches that of a compare register
(CR01n).
When bit 1 (CRC0n1) of capture/compare control register 0n (CRC0n) is 1, the count value of TM0n is captured
to CR00n in the phase reverse to that of the input signal of the TI00n pin, but the capture interrupt signal
(INTTM00n) is not generated. However, the INTTM00n interrupt is generated when the valid edge of the TI01n
pin is detected. Mask the INTTM00n signal when it is not used.
