Set P42C1 bit(bit2 of P4CON1 register) to “1”, set P42C0 bit(bit2 of P4CON0 register) to “1”, and set P42DIR
Set P41DIR-P40DIR bits(bit1-0 of P4DIR register) to “1” for specifying the P41 and P40 as input pins.
Data setting to P41C1 bit, P40C1 bit, P41C0 bit and P40C0 bit, depend on the application circuit connected to P41
Data of P42D-P40D bits (bit2-0 of P4D register) do not affect to the SSIO function, so don’t care the data for the
