The 14-pin, 2-row pin-strip header is keyed at the Pin 3 loca-
tion; 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 inch × 0.1 inch. Pin strip headers are available
from vendors such as 3M, McKenzie, and Samtec.
The BTMS, BTCK, BTRST , and BTDI signals are provided so
that 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 other pins, as shown in
Figure 26. If you are not going to use the test access port for
board testing, tie BTRST to GND and tie or pull up BTCK to
V
BTRST on the connector) or held low for proper operation of
the AD14060/AD14060L. None of the Bxxx pins (Pins 5, 7, 9,
11) are connected on the emulator probe.
The JTAG signals are terminated on the emulator probe as
listed in Table 24.
Figure 27 shows JTAG scan path connections for the
multiprocessor system.

Connecting CLKIN to Pin 4 of the emulator header is optional.
The emulator uses CLKIN only when directed to perform
operations such as starting, stopping, and single-stepping
multiple ADSP-2106xs in a synchronous manner. If these
operations do not need to occur synchronously on the multiple
processors, tie Pin 4 of the emulator header to ground.
If synchronous multiprocessor operations are needed and
CLKIN is connected, clock skew between the AD14060/
AD14060L and the CLKIN pin on the emulator header must be
minimal. If the skew is too large, synchronous operations might
be off by one cycle between processors. For synchronous multi-
processor operation, TCK, TMS, CLKIN, and EMU should be
treated as critical signals in terms of skew, and should be laid
out as short as possible on the board.
If TCK, TMS, and CLKIN are driving a large number of
ADSP-2106x’s (more than eight) in the system, treat them as a
clock tree using multiple drivers to minimize skew. (See the
ADSP-2106x User’s Manual for details).
If synchronous multiprocessor operations are not needed
(CLKIN is not connected), use appropriate parallel termination
on TCK and TMS. Note that TDI, TDO, EMU , and TRST are
not critical signals in terms of skew.
TRST is driven low until the emulator probe is turned on by the emulator
software (after the invocation command).
