SPI Verilog modules 2 SPI implementations:

1. Fully Hard for FPGA without CPU core like Spartan 6 or Cyclone 4, e.t.c. features:

   • setting bit (MSB, LSB) and bytes order (Little endian or Big endina)
   • adjustable number of extra clocks when some devices needs to make internal synchronizzation while CS is still active and clock keep going from clk (Dragster/Awaiba/Cmosis DR-2k-7)

2. Fully soft SPI with AXI Full interface with CPU.
