Passive Serial ConfigurationFigure 8–4. Software Settings for Configuring Devices Using n-Bit PS ModesAlternatively, you can daisy chain two FPGAs to one DATA line while theother DATA lines drive one device each. For example, you could use the2-bit PS mode to drive two FPGAs with DATA Bit0 (EPF10K100E andEP20K400 devices) and the third device (the EP1M350 device) with DATABit1. This 2-bit PS configuration scheme requires less space in theconfiguration flash memory, but can increase the total systemconfiguration time (Figure 8–5).8–14 Altera CorporationConfiguration Handbook, Volume 1 August 2005
