The Flash module also contains a set of 16 control and status registers located in address space module
base + 0x0000 to module base + 0x000F. In order to accommodate more than one Flash block with a
minimum register address space, a set of registers located from module base + 0x0004 to module
base + 0x000B are repeated in all banks. The active register bank is selected by the BKSEL bits in the
unbanked Flash configuration register (FCNFG). A summary of these registers is given in
their accessibility in normal and special modes is detailed in
