When MMAP = 0, on-chip program memory ROM occupies
4K words beginning at address 0x0000. Off-chip program
memory uses the remaining 12K words beginning at address
0x1000.
When MMAP = 1, 2K words of off-chip program memory begin
at address 0x0000. 2K words of on-chip program memory ROM
is at 0x0800 to 0x0FF0, and the remainder 2K words of pro-
gram memory ROM is at 0x3800 to 0x3FFF. An additional
10K of off-chip program memory is at 0x1000 to 0x37FF.

Data Memory Interface
The data memory address bus (DMA) is 14 bits wide. The
bidirectional external data bus is 24 bits wide, with the upper 16
bits used for data memory data (DMD) transfers.
The data memory select (DMS) signal indicates access to data
memory and can be used as a chip select signal. The write (WR)
signal indicates a write operation and can be used as a write
strobe. The read (RD) signal indicates a read operation and can
be used as a read strobe or output enable signal.
The ADSP-216x processors support memory-mapped I/O, with
the peripherals memory-mapped into the data memory address
space and accessed by the processor in the same manner as data
memory.
Data Memory Map
For the ADSP-2165/ADSP-2166, on-chip data memory RAM
resides in the 4K words beginning at address 0x2000, as shown
in Figure 7. Data memory locations from 0x3000 to the end of
data memory at 0x3FFF are reserved. Control and status regis-
ters for the system, timer, wait-state configuration, and serial port
operations are located in this region of memory.
The remaining 8K of data memory is located off-chip. This
external data memory is divided into three zones, each associ-
ated with its own wait-state generator. This allows slower pe-
ripherals to be memory-mapped into data memory for which
wait states are specified. By mapping peripherals into different
zones, you can accommodate peripherals with different wait-
state requirements. All zones default to 7 wait states after
RESET

For the ADSP-2161/ADSP-2162/ADSP-2163/ADSP-2164, on-
chip data memory RAM resides in the 512 words beginning at
address 0x3800, also shown in Figure 8. Data memory locations
from 0x3A00 to the end of data memory at 0x3FFF are reserved.
Control and status registers for the system, timer, wait-state
configuration, and serial port operations are located in this
region of memory.

The remaining 14K of data memory is located off-chip. This
external data memory is divided into five zones, each associated
with its own wait-state generator. This allows slower peripherals
to be memory-mapped into data memory for which wait states
are specified. By mapping peripherals into different zones, you
