INTTM002 signal is generated as an external interrupt signal.
two cycles longer than the count clock selected by prescaler mode register 02 (PRM02) (see
Figure 7-13 Example of CR01n Capture Operation (When Rising Edge Is Specified)).
The valid edge of the TI012 and TI002 pin is set by PRM02.
If ES021 and ES020 are set to 11 (both edges) when CRC021 is 1, the valid edge of the TI002 pin cannot
be detected.
If TMC023 and TMC022 are set to 11 (clear & start mode entered upon a match between TM02 and
CR002), be sure to set CRC020 to 0.
