hi_muxsel specification

Hi I’m looking for some documentation about the pin “hi_muxsel” but I couldn’t find anything. can someone give me infos about this pin and what it is used for? I’m using the XEM6001.

Please start with the XEM6001 User’s Manual.

Starting with the XEM6001 (or XEM7001) user manual is good advice, except that they both state “The end result is that your FPGA design should always tie HI_MUXSEL to 0”. “Always” is a little miss-leading.If you want to warm boot the FPGA from the flash using ICAP-Spartan6 (or ICAPE2 for Artix-7), then you need to set HI_MUXSEL to 1 during the warm boot process.
