TWI EEPROM Boot
The SPI Flash Boot program supports all Atmel DataFlash devices.
Table 11-2.
The SPI Flash Boot program supports all SPI Serial Flash devices responding correctly at both
Get Status and Continuous Read commands.
The TWI EEPROM Bootloader uses the TWI0. It uses only one valid code detection. It analyzes
the ARM exception vectors.
TWI EEPROM Boot supports all I
address 0x50.
The NVM drivers use several PIOs in peripheral mode to communicate with external memory
devices. Care must be taken when these PIOs are used by the application. The devices con-
nected could be unintentionally driven at boot time, and electrical conflicts between output pins
used by the NVM drivers and the connected devices may occur.
To assure correct functionality, it is recommended to plug in critical devices to other pins not
used by NVM.
Table 11-3
are driven during the boot sequence for a period of less than 1 second if no correct boot program
is found.
