What is the Security (Read Protect) option and how is it selected?
The Security option on the 1800 devices is an option that, when turned on, prohibits the bitstream from being read back from the PROM via JTAG. The device can, however, be erased and reprogrammed with a new bitstream.
The Security option can be set after programming the PROM using the JTAG programmer, HW-130, or other third-party programmers.
With iMPACT, you can enable Read Protect when you bring up the programming window.
