ADSP-2106x/21160 Processor Booting
ADSP-2106x/21160 Processor Booting
ADSP-2106x/21160 processors support three boot modes: EPROM, host,
link port, and no-boot (see Table 3-3 and Table 3-4 on page 3-5).
Boot-loadable files for these modes pack boot data into 48-bit instructions
and use an appropriate DMA channel of the processor’s DMA controller
to boot-load the instructions.
� ADSP-2106x
processors use DMA channel 6 (DMAC6) for booting.
ADSP-21160 processors use DMAC8 for link port booting and
DMAC10 for the host and EPROM booting.
When booting from an EPROM through the external port, the
ADSP-2106x/21160 processor reads boot data from an 8-bit external
EPROM.
When booting from a host processor through the external port, the
ADSP-2106x/21160 processor accepts boot data from a 8- or
16-bit host microprocessor.
When booting through the link port, the ADSP-2106x/21160 processor
receives boot data as 4-bit wide data in link buffer 4.
In no-boot mode, the ADSP-2106x/21160 processor begins executing
instructions from external memory.
