Notes on Port Mode Register Modification
The following points should be noted when a port mode register is modified to switch the input
capture function or the input capture input noise canceler function.
• Switching input capture input pin function

Note that when the pin function is switched by modifying TMIG in port mode register 1
(PMR1), which performs input capture input pin control, an edge will be regarded as having
been input at the pin even though no valid edge has actually been input. Input capture input
signal input edges, and the conditions for their occurrence, are summarized in table 9.14.
