INTTM003 signal is generated as an external interrupt signal.
two cycles longer than the count clock selected by prescaler mode register 03 (PRM03) (see
Figure 7-13 Example of CR01n Capture Operation (When Rising Edge Is Specified)).
The valid edge of the TI013 and TI003 pin is set by PRM03.
If ES031 and ES030 are set to 11 (both edges) when CRC031 is 1, the valid edge of the TI003 pin cannot
be detected.
If TMC033 and TMC032 are set to 11 (clear & start mode entered upon a match between TM03 and
CR003), be sure to set CRC030 to 0.
