The default configuration boot address allows the system to use special parameter
blocks in the flash memory map. Parameter blocks are at the top or bottom of the
memory map.
configuration scheme. You can change the default configuration default boot address
0×010000 to any desired address using the APFC_BOOT_ADDR JTAG instruction. For

Note to
(1) The default configuration boot address is x010000 when represented in 16-bit word addressing.

PS Configuration

You can perform PS configuration on Cyclone IV devices with an external intelligent
host, such as a MAX
cable. In the PS scheme, an external host controls the configuration. Configuration
data is clocked into the target Cyclone IV device through DATA[0] at each rising edge
of DCLK.
If your system already contains a common flash interface (CFI) flash memory, you can
use it for Cyclone IV device configuration storage as well. The MAX II PFL feature
provides an efficient method to program CFI flash memory devices through the JTAG
interface and the logic to control the configuration from the flash memory device to
the Cyclone IV device.
