Parking Register
This register is a dummy register that you should select after the end of a read or write operation.
Selecting the Parking Register places the module in a state insensitive to noise and to
electrostatic discharge (ESD), which may corrupt the Data Register content and cause the outputs
to change state.
Select the Parking Register by writing FFFF (hexadecimal) to the Address Handler.
