4-1 VHLD Sample Source
The VHDL source used can be found in the “Hardware\USB-IK01” folder of the CDROM
provided with the USB-EK01. Below is an excerpt from the VHDL source. Here, MM is defined
as “in std_logic_vector(1 downto 0)”, is connected to No. 3 and No. 4 of DIP switch, and
operates as „0‟ when ON and „1‟ when OFF. DIP switch 3 is Bit0.
While analyzing the drawing and the source together, please modify the program source so
that it can perform the desired operation.
