13.3.2 Register Descriptions
The Flash module contains a set of 20 control and status registers located between Flash module base +
0x0000 and 0x0013. A summary of the Flash module registers is given in Figure 13-4 with detailed

Writes to any Flash register must be avoided while a Flash command is
active (CCIF=0) to prevent corruption of Flash register contents and
adversely affect Memory Controller behavior.
