Figure 8. Target Board Connector for EZ-ICE
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 a 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 DSP’s data sheet. The performance of the EZ-ICE may ap-
proach published worst case specifications for some memory
access timing requirements and switching characteristics.
Note: If your target does not meet the worst case chip specifica-
tions 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 characteristics and timing requirements
within published limits.
Restriction: All memory strobe signals on the ADSP-2184 (
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.
