4.2.3. INFO Area
The INFO area is mapped into the system address space between 0x4000_0C00 and 0x4000_0FFF. No memory
location in the INFO pages can be directly written. The INFO area contains two pages of 512 bytes each:
• INFO page 0 (lower half of addresses) contains traceability information and trimming values for SBC
analog circuitry (see section 3.15). This page is only readable and cannot be accessed indirectly by the
flash controller (no WRITE, no ERASE). The INFO page 0 base address is 0x4000_0C00.
• INFO page 1 (upper half of addresses) is a mirror copy of INFO page 0 for redundancy of INFO page
data content.

4.2.4. RAM Memory 2kB
The SRAM is physically located at addresses 0x2000_0000 to 0x2000_07FF. It can be accessed (READ and
WRITE) with byte, half-word, and word size. The SRAM can also be mirrored to address 0x0000_0000 by setting
the MEMSWAP bit in register SYS_MEMPORTCFG (see Table 4.6).
