BootROM firmware selects the boot device after reset by reading the status strap [3: 0] Contact.
Static RAM (SRAM)
Some of these memory areas used during the boot phase by flash BootROM. After downloading all areas of SRAM fully available for general-purpose applications.
- 32 KB of RAM (SYSTEM0, one port). When all of the islands off the power, SYSTEM0 losing data content.
- 4K always RAM (SYSRAM1, one port). When all of the islands off the power, SYSRAM1 retains its data content.
