Hswap_en

Spartan-3 USB 2.0 Modules

Hi all

I want to know how the pin HSWAP_EN is configured on the XEM3001 board.
During power-up I don’t want to have pull-up’s on all IO’s…
Can I disconnect it without getting problems with the USB- and PLL-devices?

Kind Regards

We connected the pin directly to the power supply.
During start-up the FPGA will keep the IO-lines in high impedance state until the bit-file has been loaded.
