From the last location FF to the first 00 can be reached by increasing and from first to last by decreasing.
Once the storage location to be varied has been selected, its value can be modified by the bits that form
part of the storage location numerical buttons, numbers «0» to «7», respectively. This swithches the binary
number from and between 0 and 1 each time one of the buttons is pressed.
