Note If the valid edge of TI000 is specified to be both the rising and falling edges, 16-bit timer 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.
Remark
0/1: Setting 0 or 1 allows another function to be used simultaneously with pulse width measurement.
See the description of the respective control registers for details.
