begin_memory_edit -hardware_name "USB-Blaster \[USB-0\]" -device_name \
"@1: EP1S25/_HARDCOPY_FPGA_PROTOTYPE (0x020030DD)"
# Write memory content using binary string
write_content_to_memory -instance_index 0 -start_address 575 -word_count \
2 -content "0000001011011100"
# Read back memory content in binary string written
puts \
[read_content_from_memory -instance_index 0 -start_address 575 \
-word_count 2 ]
