The reset state of DDRK in the S12_CORE is $00, configuring the pins as inputs.
The reset state of PUPKE in the PUCR register of the S12_CORE is "1" enabling the internal pullup
resistors at PortK[2:0].
In this reset state the pull-up resistors provide a defined state and prevent a floating input, thereby
preventing unnecessary current consumption at the input stage.
