Cyclone II Device Handbook, Volume 1
The 28 data and control signals consist of four data out lines, io_dataout[3..0], four output enables,
io_coe[3..0], four input clock enables, io_cce_in[3..0], four output clock enables, io_cce_out[3..0],
four clocks, io_cclk[3..0], four asynchronous clear signals, io_caclr[3..0], and four synchronous clear
signals, io_csclr[3..0].
Each of the four IOEs in the column I/O block can have two io_datain (combinational or registered) inputs.
