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 accessible 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 guaran-
teed operation. This length restriction 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.

Figure 6. JTAG Scan Path Connections for Multiple ADSP-2106x Systems
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:
Signal

TMS

Resistor (16 mA Driver)
TCK

CLKIN One TTL Load, Split Termination (160/220)
EMU

Pull-Up Resistor, One TTL Load
(Open-Drain Output from the DSP)
*TRST is driven low until the EZ-ICE probe is turned on by the emulator at
software start-up. After software start-up,
TRST is driven high.
Figure 6 shows JTAG scan path connections for systems that
contain multiple ADSP-2106x processors.
