ADSP-2186M
Figure 12. Mode A Pin/EZ-ICE Circuit
See the ADSP-2100 Family EZ-Tools data sheet for complete
information on ICE products.
The ICE-Port interface consists of the following ADSP-2186M
pins:
EBR
,
EINT
, EE,
EBG
, ECLK,
ERESET
, ELIN,
EMS
,
and ELOUT
These ADSP-2186M 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-2186M
and the connector must be kept as short as possible, no longer
than 3 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-2186M 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.

Figure 13. Target Board Connector for EZ-ICE
The 14-pin, 2-row pin strip header is keyed at the Pin 7 loca-
tion—Pin 7 must be removed 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
emulator, 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 tim-
ing 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. Depend-
ing on the severity of the specification violation, you may have
trouble manufacturing your system as DSP components statisti-
cally vary in switching characteristic and timing requirements
within published limits.
Restriction: All memory strobe signals on the ADSP-2186M
(
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 Emulator
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 asserted
by the EZ- ICE board’s DSP.
