ADSP-2189M

The ICE-Port interface consists of the following ADSP-2189M
pins:
EBR
,
EINT
, EE,
EBG
, ECLK,
ERESET
, ELIN,
EMS
,
and ELOUT.
These ADSP-2189M pins must be connected only to the EZ-
ICE connector in the target system. These pins have no function
except during emulation, and do not require pull-up or pull-
down resistors. The traces for these signals between the ADSP-
2189M and the connector must be kept as short as possible, no
longer than three inches.
The following pins are also used by the EZ-ICE:
BR
,
BG
,
RESET
, and GND.
The EZ-ICE uses the EE (emulator enable) signal to take con-
trol of the ADSP-2189M in the target system. This causes the
processor to use its
ERESET
,
EBR
, and
EBG
pins instead of
the
RESET
,
BR
, and
BG
pins. The
BG
output is three-stated.
These signals do not need to be jumper-isolated in your system.
The EZ-ICE connects to your target system via a ribbon cable
and a 14-pin female plug. The female plug is plugged onto the
14-pin connector (a pin strip header) on the target board.
Target Board Connector for EZ-ICE Probe
The EZ-ICE connector (a standard pin strip header) is shown in
Figure 13. You must add this connector to your target board
design if you intend to use the EZ-ICE. Be sure to allow enough
room in your system to fit the EZ-ICE probe onto the 14-pin
connector.

The 14-pin, 2-row pin strip header is keyed at the Pin 7 loca-
tion—you must remove Pin 7 from the header. The pins must
be 0.025 inch square and at least 0.20 inch in length. Pin spac-
ing should be 0.1
×
0.1 inches. The pin strip header must have
at least 0.15 inch clearance on all sides to accept the EZ-ICE
probe plug.
Pin strip headers are available from vendors such as 3M,
McKenzie, and Samtec.
Target Memory Interface
For your target system to be compatible with the EZ-ICE emu-
lator, it must comply with the memory interface guidelines listed
below.
PM, DM, BM, IOM, and CM
Design your Program Memory (PM), Data Memory (DM),
Byte Memory (BM), I/O Memory (IOM), and Composite
Memory (CM) external interfaces to comply with worst case
device timing requirements and switching characteristics as
specified in this data sheet. The performance of the EZ-ICE
may approach published worst case specification for some memory
access timing requirements and switching characteristics.
Note: If your target does not meet the worst case chip specifica-
tion for memory access parameters, you may not be able to
emulate your circuitry at the desired CLKIN frequency. De-
pending on the severity of the specification violation, you may
have trouble manufacturing your system as DSP components
statistically vary in switching characteristic and timing require-
ments within published limits.
Restriction:
All memory strobe signals on the ADSP-2189M
(
RD
,
WR
,
PMS
,
DMS
,
BMS
,
CMS
, and
IOMS
) used in your
target system must have 10 k
pull-up resistors connected when
the EZ-ICE is being used. The pull-up resistors are necessary
because there are no internal pull-ups to guarantee their state
during prolonged three-state conditions resulting from typical
EZ-ICE debugging sessions. These resistors may be removed at
your option when the EZ-ICE is not being used.
Target System Interface Signals
When the EZ-ICE board is installed, the performance on some
system signals change. Design your system to be compatible
with the following system interface signal changes introduced by
the EZ-ICE board:
EZ-ICE emulation introduces an 8 ns propagation delay
between your target circuitry and the DSP on the
RESET
signal.
EZ-ICE emulation introduces an 8 ns propagation delay
between your target circuitry and the DSP on the
BR
signal.
EZ-ICE emulation ignores
RESET
and
BR
when single-
stepping.
EZ-ICE emulation ignores
RESET
and
BR
when in Emula-
tor Space (DSP halted).
EZ-ICE emulation ignores the state of target
BR
in certain
modes. As a result, the target system may take control of the
DSP’s external memory bus only if bus grant (
BG
) is as-
serted by the EZ-ICE board’s DSP.
