Functional Description and Application Information
4.36.3.2
The Flash IFR is a 128 byte nonvolatile information memory that is read accessible as defined in the SoC Guide. The MCU
memory map places the Flash IFR addresses between Flash IFR base + 0x0000 and 0x007F as shown in
4.36.3.3
The Flash module contains a set of 16 control and status registers located between Flash register base + 0x0000 and 0x000F.
Flash registers are byte and word accessible. A summary of the Flash module registers is given in
descriptions of each register bit are provided in the following sections.
