-- Example code to read/write user logic slave model s/w accessible registers
--
-- Note:
-- The example code presented here is to show you one way of reading/writing
-- software accessible registers implemented in the user logic slave model.
-- Each bit of the Bus2IP_WrCE/Bus2IP_RdCE signals is configured to correspond
-- to one software accessible register by the top level template. For example,
-- if you have four 32 bit software accessible registers in the user logic,
-- you are basically operating on the following memory mapped registers:
--
-- Bus2IP_WrCE/Bus2IP_RdCE Memory Mapped Register
-- "1000" C_BASEADDR + 0x0
-- "0100" C_BASEADDR + 0x4
-- "0010" C_BASEADDR + 0x8
-- "0001" C_BASEADDR + 0xC

-- Description: Converter inteneded to connect a SVGACTRL core to a Chrontel
-- CH7301C DVI transmitter. Multiplexes data and generates clocks.
-- Tailored for use on the Xilinx ML50x boards with Leon3/GRLIB
-- template designs.
--
-- This multiplexer has been developed for use with the Chrontel CH7301C DVI
-- transmitter. Supported multiplexed formats are, as in the CH7301 datasheet:
--
-- IDF Description
-- 0 12-bit multiplexed RGB input (24-bit color), (scheme 1)
-- 1 12-bit multiplexed RGB2 input (24-bit color), (scheme 2)
-- 2 8-bit multiplexed RGB input (16-bit color, 565)
-- 3 8-bit multiplexed RGB input (15-bit color, 555)
--
-- This core assumes a 100 MHz input clock on the 'clk' input.
--
-- If the generic 'dynamic' is non-zero the core uses the value vgao.bitdepth
-- to decide if multiplexing should be done according to IDF 0 or IDF 2.
-- vago.bitdepth = "11" gives IDF 0, others give IDF2.
-- The 'idf' generic is not used when the 'dynamic' generic is non-zero.
-- Note that if dynamic selection is enabled you will need to reconfigure
-- the DVI transmitter when the VGA core changes bit depth.
