PRELIMINARY TECHNICAL DATA
Also, the clearance (length, width, and height) around the header
must be considered. Leave a clearance of at least 0.15" and 0.10"
around the length and width of the header, and reserve a height
clearance to attach and detach the pod connector.
As can be seen in Figure 6, there are two sets of signals on the
header. There are the standard JTAG signals TMS, TCK, TDI,
TDO,
TRST, and EMU used for emulation purposes (via an
emulator). There are also secondary JTAG signals BTMS,
BTCK, BTDI, and
BTRST that are optionally used for board-
level (boundary scan) testing.
When the emulator is not connected to this header, place jumpers
across BTMS, BTCK,
BTRST, and BTDI as shown in Figure 7.
This holds the JTAG signals in the correct state to allow the DSP
to run free. Remove all the jumpers when connecting the
emulator to the JTAG header.
JTAG Emulator Pod Connector
Figure 8 details the dimensions of the JTAG pod connector at the
14-pin target end. Figure 9 displays the keep-out area for a target
board header. The keep-out area allows the pod connector to
properly seat onto the target board header. This board area
should contain no components (chips, resistors, capacitors, etc.).
The dimensions are referenced to the center of the 0.25" square
post pin.
