When performing noise canceler function switching by modifying NCS in port mode register 2
(PMR2), which controls the input capture input noise canceler, TMIG should first be cleared to
0. Note that if NCS is modified without first clearing TMIG, 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 9.15.

pin is not set as an input capture input pin, the timer G input capture input
Conditions
When TMIG is modified from 0 to 1 while the TMIG pin is high
When NCS is modified from 0 to 1 while the TMIG pin is high, then
TMIG is modified from 0 to 1 before the signal is sampled five times by
the noise canceler
When TMIG is modified from 1 to 0 while the TMIG pin is high
When NCS is modified from 0 to 1 while the TMIG pin is low, then
TMIG is modified from 0 to 1 before the signal is sampled five times by
the noise canceler
When NCS is modified from 0 to 1 while the TMIG pin is high, then
TMIG is modified from 1 to 0 after the signal is sampled five times by
the noise canceler
Conditions
When the TMIG pin is modified from 0 to 1 while TMIG is 1, then NCS
is modified from 0 to 1 before the signal is sampled five times by the
noise canceler
When the TMIG pin is modified from 1 to 0 while TMIG is 1, then NCS
is modified from 1 to 0 before the signal is sampled five times by the
noise canceler
