Interconnect
The 32 data and control signals consist of eight data out lines: four lines each for DDR applications
io_dataouta[3..0] and io_dataoutb[3..0], four output enables io_oe[3..0], four input clock enables
io_ce_in[3..0], four output clock enables io_ce_out[3..0], four clocks io_clk[3..0], four asynchronous
clear and preset signals io_aclr/apreset[3..0], and four synchronous clear and preset signals
io_sclr/spreset[3..0].
