Memory organization
The Flash program memory is organized in 32-bit wide memory cells which can be used for
storing both code and data constants.
You can Program Bank 0 and Bank 1 independently, i.e. you can read from one bank while
writing to the other.
The on-chip Flash is divided in 2 banks that can mapped independently in the 64 MByte
address space 0x0000-0000 - 0x03FF.FFF by programming the FMI registers.
The STR91xFAxx2 embedded Flash Module is organized as shown in Table 1.
The STR91xFAxx4 embedded Flash Module is organized as shown in Table 2.
