23-44 ADSP-214xx SHARC Processor Hardware Reference
These kernel files (DXE, ASM) are supplied with the VisualDSP++ devel-
opment tools for all boot modes. For more information on the kernels,
refer to the tools documentation
Boot Master/Slave
How a processor boots is dependent on the peripheral used. See “Proces-
sor Booting” on page 23-7.
Boot Modes
The boot mode is identified by the
BOOT_CFG2-0 pins that are used in the
boot process.
No Boot Mode
In legacy mode, the processor does not boot. Instead, it starts fetching
instructions directly from external memory. The SHARC ADSP-214xx
processors onwards do not support this mode.
ROM Boot Mode
For BOOT_CFG2-0 pins = 011, the processor executes from internal ROM.
Only specific versions of the processors support this mode.
