Concurrent ConfigurationFigure 3–1. Software Settings for Configuring Devices Using n-Bit PS ModesAlternatively, you can daisy chain two SRAM-based devices to one DATAline while the other DATA lines drive one device each. For example, youcould use the 2-bit PS mode to drive two SRAM-based devices with DATABit0 (EP20K100E and EP20K60E devices) and the third device (theEP20K200E device) with DATA Bit1. This 2-bit PS configuration schemerequires less space in the configuration flash memory, but may increasethe total system configuration time (Figure 3–2).3–4 Altera CorporationConfiguration Handbook, Volume 2 April 2007
