Preliminary
The 21 data and control signals consist of three data out lines, io_dataout[2..0], three output enables,
io_coe[2..0], three input clock enables, io_cce_in[2..0], three output clock enables, io_cce_out[2..0],
three clocks, io_cclk[2..0], three asynchronous clear signals, io_caclr[2..0], and three synchronous clear
signals, io_csclr[2..0].
Each of the three IOEs in the column I/O block can have one io_datain input (combinatorial or registered) and
one comb_io_datain (combinatorial) input.
