JTAG Interface
The JTAG emulation port allows an emulator to access the processor’s
internal and external memory through a six-pin interface. The JTAG emu-
lator port of the processor can be accessed via the on-board USB debug
agent or with an external emulator via the JTAG connector (
ZP4
). When
an external emulator connects to the board, the on-board USB debug
agent is disabled. See
“JTAG Connector (ZP4)” on page 2-33
information.

.
Expansion Interface
The expansion interface consists of three 90-pin connectors (
J1—3
). These
connectors contain a majority of the ADSP-BF527 processor’s signals. For
the pinout of the connectors, go to
. The expansion interface allows an EZ-Extender or a
custom-design daughter board to be tested across various hardware plat-
forms. The mechanical dimensions of the expansion connectors can be
obtained by contacting

Analog Devices offers many EZ-Extender products. For more information
about EZ-Extenders, visit the Analog Devices Web site at:

.
Limits to current and interface speed must be taken into consideration
when using the expansion interface. Because current for the expansion
interface is sourced from the EZ-KIT Lite, the current should be limited
to 1A for both the 5V and 3.3V planes. If more current is required, then a
