Passive Serial
Configuration
PS configuration of Stratix II and Stratix II GX devices can be performed
using an intelligent host, such as a MAX II device or microprocessor with
flash memory, an Altera configuration device, or a download cable. In the
PS scheme, an external host (MAX II device, embedded processor,
configuration device, or host PC) controls configuration. Configuration
data is clocked into the target Stratix II or Stratix II GX device via the
DATA0 pin at each rising edge of DCLK.
1 The Stratix II and Stratix II GX decompression and design
security features are fully available when configuring your
Stratix II or Stratix II GX device using PS mode.
Table 7–14 shows the MSEL pin settings when using the PS configuration
scheme.

Note to Table 7–14:
(1) This scheme requires that you drive the RUnLU pin to specify either remote
update or local update. For more information about remote system upgrade in
Stratix II devices, refer to the Remote System Upgrades With Stratix II &
Stratix II GX Devices chapter in volume 2 of the Stratix II Device Handbook or the
Remote System Upgrades With Stratix II & Stratix II GX Devices chapter in volume 2
of the Stratix II GX Device Handbook.
