Configuration parameters and macros

The configuration parameter which is used for SSD operations is explained in this section.

The configuration parameters are handled as structure. The user should correctly initialize the fields including c90flRegBase, mainArrayBase, shadowRowBase, shadowRowSize,

pageSize and BDMEnable before passing the structure to SSD functions. The pointer to

CallBack has to be initialized either to a null pointer or a valid CallBack function pointer.
