EAB Local
Interconnect (2)
All registers can be asynchronously cleared by EAB local interconnect signals, global signals, or the chip-wide reset.
EPF10K30E and EPF10K50E devices have 88 EAB local interconnect channels; EPF10K100E, EPF10K130E, and
EPF10K200E devices have 104 EAB local interconnect channels.

The EAB can also be used for bidirectional, dual-port memory
applications where two ports read or write simultaneously. To implement
this type of dual-port memory, two EABs are used to support two
simultaneous read or writes.
Alternatively, one clock and clock enable can be used to control the input
registers of the EAB, while a different clock and clock enable control the
output registers (see
