Programmable delays can increase the register-to-pin delays for output
and/or output enable registers. A programmable delay exists to increase
the t
Table 4–21
The IOE registers in Stratix GX devices share the same source for clear or
preset. You can program preset or clear for each individual IOE. You can
also program the registers to power up high or low after configuration is
complete. If programmed to power up low, an asynchronous clear can
control the registers. If programmed to power up high, an asynchronous
preset can control the registers. This feature prevents the inadvertent
activation of another device’s active-low input upon power-up. If one
register in an IOE uses a preset or clear signal then all registers in the IOE
must use that same signal if they require preset or clear. Additionally, a
synchronous reset signal is available for the IOE registers.
Double-Data Rate I/O Pins
Stratix GX devices have six registers in the IOE, which support DDR
interfacing by clocking data on both positive and negative clock edges.
The IOEs in Stratix GX devices support DDR inputs, DDR outputs, and
bidirectional DDR modes.
