After ProgramFPGA() is called and the FPGA design is completely downloaded, the pin
#RESET (note: the prefix # means, that the signal is active low) is automatically pulsed
(HIGH/LOW/HIGH). This signal can be used for resetting the FPGA design. The API-
function ResetFPGA() can be called to initiate a pulse on #RESET at a user given time.
The following sections will give you a brief introduction about the data transfer from and to
the FPGA over the Cypress FX-2 USB peripheral controller's slave FIFO interface, the
WISHBONE interconnection architecture and the provided peripheral controllers.
CESYS USB cards use only slave FIFO mode for transferring data. For further information
about the FX-2 slave FIFO mode see Cypress FX-2 user manual and datasheet and about
the WISHBONE architecture see specification B.3 (wbspec_b3.pdf).
