ML401/ML402/ML403 Evaluation Platform

UG080 (v2.5)  May 24, 2006

Detailed Description

R

29. DONE LED

The DONE LED indicates the status of the DONE pin on the FPGA. It should be lighted 
when the FPGA is successfully configured.

30. Program Switch

This switch grounds the FPGA's Prog pin when pressed. This action clears the FPGA.

31. Configuration Address and Mode DIP Switches

This 6-position DIP switch controls the configuration address and FPGA configuration 
mode.

The three leftmost switches choose one of eight possible configuration addresses. These 
three DIP switches provide the System ACE controller and the CPLD the possibility of 
using up to eight different configuration images as set by these three switches. The 
Platform Flash memory supports up to four different images.

The three rightmost DIP switches set the FPGA configuration mode pins M2, M1, and M0 
as shown in 

Table 15

.

32. Encryption Key Battery 

An onboard battery holder is connected to the V

BATT

 pin of the FPGA to hold the 

encryption key for the FPGA. A 12-mm lithium coin battery (3V), such as Panasonic part 
numbers BR1216, CR1216, and BR1225, or any other appropriate 12-mm lithium coin 
battery (3V) can be used.

33. Configuration Source Selector Switch 

The configuration source selector switch (SW12) selects between System ACE, Platform 
Flash, and linear flash/CPLD methods of programming the FPGA. Whichever method is 
selected to program the FPGA, make sure the FPGA configuration mode switches are set 
appropriately for the desired method of configuration. The PC4 connector allows JTAG 
download and debug of the board regardless of the setting of the configuration source 
selector switch.
