Signal coming from touch key.
When any one of G-1 line keys on key matrix is touched, a corresponding signal from
P10 - P17 will be input into P27. When no key is touched, the signal is held at “L” level.
Signal similar to P27.
When any one of G-2 line key on key matrix is touched, a corresponding signal will
be input into P26.
Signal similar to P27.
When any one of G-3 line key on key matrix is touched, a corresponding signal will
be input into P25.
Signal similar to P27.
When any one of G-4 line key on key matrix is touched, a corresponding signal will
be input into P24.
