INIT1355.C - sample code demonstrating the initialization of the SED1355.
The code in this example will perform initialization to the following
specification:
- 640 x 480 dual 16-bit color passive panel.
- 75 Hz frame rate.
- 8 BPP (256 colors).
- 33 MHz input clock.
- 2 MB of 60 ns EDO memory.
This means:
1) Generic C is used. I assume that pointers can access the
2) Register setup is done with discrete writes rather than being
3) The pointer assignment for the register offset does not work on

i.e. using the 1355B0B card on an x86 16 bit platform will require
table driven. This allows for clearer commenting. A real program
would probably store the register settings in an array and loop
through the array writing each element to a control register.
