Power-On-Self Test
1-20 ADSP-BF609 EZ-KIT Lite Evaluation System Manual
Power-On-Self Test
The Power-On-Self-Test Program (POST) tests all EZ-KIT Lite peripher-
als and validates functionality as well as connectivity to the processor.
Once assembled, each EZ-KIT Lite if fully tested for an extended period
of time with POST. All EZ-KIT Lite boards are shipped with POST pre-
loaded into one of their on-board flash memories. The POST is executed
by resetting the board and pressing the proper push button(s). The POST
also can be used as a reference for a custom software design or hardware
troubleshooting. Note that the source code for the POST program is
included in the EZ-KIT Lite installation directory along with the
readme.txt file, which describes how the board is configured to run
POST.
Expansion Interface III
The Expansion Interface III (EI3) allows an Analog Devices
EZ-Extender
®
or a custom-design daughter board to be tested across vari-
ous hardware platforms that have the same expansion interface.
The EI3 implemented on the ADSP-BF609 EZ-KIT Lite consists of five
connectors, P1A, P1B, P1C, P2A, and P3A. The connectors contain a major-
ity of the processor's signals. For pinout information, go to “ADSP-BF609
EZ-KIT Lite Schematic” on page B-1. The mechanical dimensions of the
expansion connectors can be obtained by contacting “Technical or Cus-
tomer Support”.

Limits to current and interface speed must be taken into consideration
when using the EI3. Current for the EI3 can be sourced from the EZ-KIT
