Figure 4. Program Memory
Program Memory (Host Mode)
allows access to all internal
memory. External overlay access is limited by a single external
address line (A0). External program execution is not available
in host mode due to a restricted data bus that is 16-bits wide
only.

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-2187L has 32K words on Data
Memory RAM on chip, consisting of 16,352 user-accessible lo-
cations and 32 memory-mapped registers. Support also exists
for up to two 8K external memory overlay spaces through the
external data bus. All internal accesses complete in one cycle.
Accesses to external memory are timed using the wait states
specified by the DWAIT register.
