The 35 data and control signals consist of five data out lines, io_dataout[4..0], five output enables,
io_coe[4..0], five input clock enables, io_cce_in[4..0], five output clock enables, io_cce_out[4..0],
five clocks, io_cclk[4..0], five asynchronous clear signals, io_caclr[4..0], and five synchronous clear
signals, io_csclr[4..0].
Each of the five IOEs in the row I/O block can have two io_datain (combinational or registered) inputs.
