Related Information
18 For configurations less that two bytes wide, Xilinx* write enable signals (wea and web) are equivalent to Intel® FPGA write enable signals (wren, wren_a, or wren_b) signals, depending on the memory mode used. For configurations of more than two bytes, Xilinx* 's write enable buses (wea[] and web[]) are equivalent to Intel® FPGA byte enable buses(byteena[], byteena_a[], or byteena_b[]), depending on the memory mode used. Also, the Intel® FPGA write enable signal needs to be asserted for the write operation.

20 Port mappings denoted with NA are not applicable for that memory mode; port-mappings denoted with — are not supported in Intel® FPGA memory.
