Detailed Description

FPGA INIT and DONE LEDs

The typical Xilinx FPGA power up and configuration status LEDs are present on the
ML605.

The red INIT LED DS31 comes on momentarily after the FPGA powers up and during its
internal power-on process. The DONE LED DS13 comes on after the FPGA programming
bitstream has been downloaded and the FPGA successfully configured.

17. User I/O

The ML605 provides the following user and general purpose I/O capabilities:

User LEDs (8) with parallel wired GPIO male pin header

User Pushbutton (5) switches with associated direction LEDs

CPU Reset pushbutton switch

User DIP switch (8-pole)

User SMA GPIO

LCD Display (16 char x 2 lines)
