Note: * The switchover is seen as a falling edge of the clock pulse, and TCG is incremented.
Note on Rewriting Port Mode Registers: When a port mode register setting is modified to
enable or disable the input capture function or input capture noise canceling function, note the
following points.

Switching the function of the input capture pin
When the function of the input capture pin is switched by modifying the TMIG bit in port
mode register 1 (PMR1) an input capture edge may be recognized even though no valid signal
edge has been input. This occurs under the conditions listed in table 9.18.
