The Flash module also contains a set of 16 control and status registers located in address space module
base + 0x0000 to module base + 0x000F. A summary of these registers is given in Table 2-3 while their
accessibility in normal and special modes is detailed in Section 2.3.2, “Register Descriptions”.
