Stellaris^® LM4F111H5QR Microcontroller
Register 10: Flash Size (FSIZE), offset 0xFC0
This register indicates the size of the on-chip Flash memory.
Important: This register should be used to determine the size of the Flash memory that is
implemented on this microcontroller. However, to support legacy software, the DC0
register is available. A read of the DC0 register correctly identifies legacy memory sizes.
Software must use the FSIZE register for memory sizes that are not listed in the DC0
register description.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Flash Size
Indicates the size of the on-chip Flash memory.
