T he EZ-ICE uses the ICE-Port’s EE (emulator enable) signal to
take control of the target ADSP-2181. T his causes the DSP to
automatically use its
ERESET
,
EBR
, and
EBG
pins instead of
the
RESET
,
BR
, and
BG
pins. T he
BG
output is tristated.
And, unlike many other emulators, these signals do not need to
be jumper-isolated in your system when the EZ-ICE is installed.
Restrictions
If you are using the external memory bus in your target system,
all memory strobe signals being used on the ADSP-2181 (
RD
,
WR
,
PMS
,
DMS
,
BMS
,
CMS
and
IOMS
) must have a 10 k
pull-up resistor connected when the EZ-ICE is being used. T he
pull-up resistors are necessary because there are no internal
pull-ups to guarantee their state during prolonged tristate
conditions resulting from typical EZ-ICE debugging sessions.
T hese resistors may be removed at your option when the EZ-
ICE is not being used.
Interconnection
T he EZ-ICE for the ADSP-2181 uses a 10-inch long ribbon
cable to connect to the target board. T he ribbon cable is
permanently attached to the EZ-ICE and is terminated with a
standard 2-row
×
7-pin (0.100
×
0.100 inch pin spacing) female
IDS connector. T he mating ICE-Port connector on the target
board should be a 2-row
×
7-pin male (0.025-inch square pins,
minimum 0.20-inches long) pin strip header (available from
such vendors as 3M, McK enzie, and Samtec). T his connector
is necessary if you intend to use the ADSP-2181 EZ-ICE. T he
length of traces between this connector and the DSP should be
kept as short as possible; no more than 3-inches long. Figure 4
shows the target board connector and the pin assignments. Pins
shown with a “*” notation must be connected only to the ICE-
Port connector.

ADSP-2171 T arget System Requirements
T o provide emulator interface capability to your target DSP
board design, you must add a pair of 45-pin male headers to
your board. T he EZ-ICE’s ADDS-21xx Emulator Board (EB)
plugs directly onto the connectors, becoming a daughter card
to your target system. Figure 2 shows how this is accomplished
and some of the critical dimensions involved. (Note: Pin strip
headers should be SAMT EC part number T SW-115-07-S-T
or equivalent.) It is important that there is approximately
0.40 inches clearance around the connectors.
