In thePS scheme, an external host (MAX II device, embedded processor,configuration device, or host PC) controls configuration. Configurationdata is clocked into the target Stratix II or Stratix II GX device via theDATA0 pin at each rising edge of DCLK.1 The Stratix II and Stratix II GX decompression and designsecurity features are fully available when configuring yourStratix II or Stratix II GX device using PS mode.Table 7–14 shows the MSEL pin settings when using the PS configurationscheme.Table 7–14.
