The APEX 20K architecture supports several configuration schemes. This
section summarizes the device operating modes and available device
configuration schemes.
Operating Modes
The APEX architecture uses SRAM configuration elements that require
configuration data to be loaded each time the circuit powers up. The
process of physically loading the SRAM data into the device is called
configuration. During initialization, which occurs immediately after
configuration, the device resets registers, enables I/O pins, and begins to
operate as a logic device. The I/O pins are tri-stated during power-up,
and before and during configuration. Together, the configuration and
initialization processes are called command mode; normal device operation
is called user mode.
Before and during device configuration, all I/O pins are pulled to V
by a built-in weak pull-up resistor.
