Tristate Register Block
The tristate register block provides the ability to register tri-state control signals from the core of the device before
they are passed to the sysIO buffers. The block contains a register for SDR operation and an additional latch for
DDR operation. Figure 2-30 shows the diagram of the Tristate Register Block.
In SDR mode, ONEG1 feeds one of the
fl
ip-
fl
ops that then feeds the output. The
fl
ip-
fl
op can be con
fi
gured a D-
type or latch. In DDR mode, ONEG1 is fed into one register on the positive edge of the clock and OPOS1 is
latched. A multiplexer running off the same clock selects the correct register for feeding to the output (D0).
