In case of a sine signal (let's say sel = '1'), the counter will represent the phase and will be used as input to your sine lookup table (that you, by the way, could initialize with a VHDL function calculating the lookup table content instead of providing precalculated literals). The output of the sine lookup table is your dataout output.

The issue is subtle as basic to VHDL signals. You assign values to signals in the process and expect them to be immediately available. That does not occur. No signal is updated while any process has yet to have been resumed and subsequently suspended in the current simulation cycle.

Incorrect parameters may make the output inaccurate or plain wrong. Two wrappers are available which set the parameters for a sensible balance between accuracy and efficiency: sincos_gen_d18_p20.vhdl is for 18-bit sine/cosine output. sincos_gen_d24_p26.vhdl is for 24-bit sine/cosine output.

A GPIO pin can be either a zero or a one. To output a parallel signal, you need to declare a std_logic_vector and assign a set of pins. R8 is the input of a 50MHz clock. You'll probably want to divide that down quite a bit before you try …
