Notes to Table 9–2:
(1) In these modes, the host system must send a DCLK that is x4 the data rate.
(2) Remote system upgrade is only available in the fast AS configuration scheme. Local update mode is not supported in the fast AS configuration
scheme.
Refer to the following for the configuration features supported in Arria II devices:
■ For more information about the configuration data decompression feature, refer to
“Configuration Data Decompression” on page 9–46.
■ For more information about the remote system upgrade feature, refer to “Remote
System Upgrades” on page 9–48.
■ For more information about the design security feature, refer to the “Design
Security” on page 9–61.
■ For more information about the parallel flash loader (PFL), refer to Parallel Flash
Loader Megafunction User Guide.
If your system already contains a common flash interface (CFI) flash memory device,
you can also use it for the Arria II device configuration storage. The PFL feature in
MAX II devices provides an efficient method to program CFI flash memory devices
through the JTAG interface and provides the logic to control configuration from the
flash memory device to the Arria II device. Both passive serial (PS) and fast passive
parallel (FPP) configuration modes are supported using this PFL feature.
For more information about programming Altera serial configuration devices, refer to
“Programming Serial Configuration Devices” on page 9–24.
