load acts as a preset when the asynchronous load data input is tied high.
When the asynchronous load/preset signal is used, the labclkena0
signal is no longer available.
The LAB row clocks [5..0] and LAB local interconnect generate the
LAB-wide control signals. The MultiTrack™ interconnects have
inherently low skew. This low skew allows the MultiTrack interconnects
to distribute clock and control signals in addition to data.
