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