Program Memory
Program Memory (Full Memory Mode) is a 24-bit-wide
space for storing both instruction opcodes and data. The
ADSP-218xN series has up to 48K words of Program
Memory RAM on chip, and the capability of accessing up
to two 8K external memory overlay spaces, using the exter-
nal data bus.
Program Memory (Host Mode) allows access to all internal
memory. External overlay access is limited by a single exter-
nal address line (A0). External program execution is not
available in host mode due to a restricted data bus that is
only 16 bits wide.
Data Memory
Data Memory (Full Memory Mode) is a 16-bit-wide space
used for the storage of data variables and for memory-
mapped control registers. The ADSP-218xN series has up
to 56K words of Data Memory RAM on-chip. Part of this
space is used by 32 memory-mapped registers. Support also
exists for up to two 8K external memory overlay spaces
through the external data bus. All internal accesses com-
plete in one cycle. Accesses to external memory are timed
using the wait states specified by the DWAIT register and
the wait state mode bit.
Data Memory (Host Mode) allows access to all internal
memory. External overlay access is limited by a single exter-
nal address line (A0).
