Note When the valid edge is detected from the TI010 pin, the capture operation is not performed but the

CRC00 is the register that controls the operation of CR000 and CR010.
Changing the value of CRC00 is prohibited during operation (when TMC003 and TMC002 = other than 00).
CRC00 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears CRC00 to 00H.

INTTM000 signal is generated as an external interrupt signal.
two cycles longer than the count clock selected by prescaler mode register 00 (PRM00).
The valid edge of the TI010 and TI000 pin is set by PRM00.
If ES001 and ES000 are set to 11 (both edges) when CRC001 is 1, the valid edge of the TI000 pin cannot
be detected.
If TMC003 and TMC002 are set to 11 (clear & start mode entered upon a match between TM00 and
CR000), be sure to set CRC000 to 0.
