17.3.2 Register Descriptions<br />

The Flash module contains a set of 20 control and status registers located between Flash module base +<br />

0x0000 and 0x0013.<br />

In the case of the writable registers, the write accesses are forbidden during Fash command execution (for<br />

more detail, see Caution note in Section 17.3).<br />

A summary of the Flash module registers is given in Figure 17-3 with detailed descriptions in the<br />

following subsections.<br />
