TARGET BOARD CONNECTOR FOR EZ-ICE PROBE
The ADSP-2106x EZ-ICE Emulator uses the IEEE 1149.1
JTAG test access port of the ADSP-2106x to monitor and control
the target board processor during emulation. The EZ-ICE
probe requires the ADSP-2106x’s CLKIN, TMS, TCK,
TRST, TDI, TDO, EMU, and GND signals be made acces-
sible on the target system via a 14-pin connector (a 2 row × 7
pin strip header) such as that shown in Figure 5. The EZ-ICE
probe plugs directly onto this connector for chip-on-board
emulation. You must add this connector to your target board
design if you intend to use the ADSP-2106x EZ-ICE. The total
trace length between the EZ-ICE connector and the furthest
device sharing the EZ-ICE JTAG pins should be limited to 15
inches maximum for guaranteed operation. This length restric-
tion must include EZ-ICE JTAG signals that are routed to one
or more ADSP-2106x devices, or a combination of ADSP-
2106x devices and other JTAG devices on the chain.

The 14-pin, 2-row pin strip header is keyed at the Pin 3 location —
Pin 3 must be removed from the header. The pins must be
0.025 inch square and at least 0.20 inch in length. Pin spacing
should be 0.1 × 0.1 inches. Pin strip headers are available from
vendors such as 3M, McKenzie and Samtec.
The BTMS, BTCK, BTRST and BTDI signals are provided so
the test access port can also be used for board-level testing.
When the connector is not being used for emulation, place
jumpers between the Bxxx pins and the xxx pins. If the test
access port will not be used for board testing, tie BTRST to GND
and tie or pull BTCK up to VDD. The TRST pin must be
asserted after power-up (through BTRST on the connector) or
held low for proper operation of the ADSP-2106x. None of the
Bxxx pins (Pins 5, 7, 9, 11) are connected on the EZ-ICE probe.
The JTAG signals are terminated on the EZ-ICE probe as
follows:
