111 : Schmitt input , VT += 0.70VCCE, AVT -= 0.50VCCE
Note 1.When the multipurpose port function pin is selected (Set bit corresponding Px operation mode register(PxMOD) to "0".),
setting value for WFnSEL is invalid and threshold switch function is effective.
Note 2. Upon exiting reset, VTnSEL1 bit value is "1" and the other bit is set to "0" .
