Note If the valid edge of TI000 pin is specified to be both the rising and falling edges, 16-bit timer
Remark 0/1: Setting 0 or 1 allows another function to be used simultaneously with pulse width measurement.
Figure 6-23. Control Register Settings for Pulse Width Measurement with Free-Running Counter and
capture/compare register 000 (CR000) cannot perform the capture operation. When the CRC001 bit value
is 1, the TM00 count value is not captured in the CR000 register when a valid edge of the TI010 pin is
detected, but the input from the TI010 pin can be used as an external interrupt source because INTTM000 is
generated at that timing.
