Notes to Table 8–1:
(1) These schemes require that you drive the RUnLU pin to specify either remote update or local update mode. AS
schemes only support the remote update mode.
(2) These modes are only supported when using a MAX II device or microprocessor and flash for configuration. In
these modes, the host system must output a DCLK that is 4 x the data rate.
(3) The EPCS16 and EPCS64 serial configuration devices support a DCLK up to 40 MHz; other EPCS devices support
a DCLK up to 20 MHz. See the Serial Configuration Devices (EPCS1, EPCS4, EPCS16, EPCS64, and EPCS128) Data
Sheet in volume 2 of the Configuration Handbook for more information.
Configuration Image Types and Pages
When using remote system upgrade, FPGA configuration bitstreams are
classified as factory configuration images or application configuration
images. An image, also referred to as a configuration, is a design loaded
into the FPGA that performs certain user-defined functions. Each FPGA
in your system requires one factory image and one or more application
