24.3.2 Register Descriptions
The Flash module contains a set of 20 control and status registers located between Flash module base +
0x0000 and 0x0013.
In the case of the writable registers, the write accesses are forbidden during Fash command execution (for
more detail, see Caution note in Section 24.3).
A summary of the Flash module registers is given in Figure 24-4 with detailed descriptions in the
following subsections.
