epson 13506 sample program code

/*
**============================================================================
**  INIT13506.C - sample code demonstrating the initialization of the S1D13506.
**
**  The code in this example will perform initialization to the following
**  specification:
**
**  - 640 x 480 dual 16-bit color passive panel.
**  - 78 Hz frame rate.
**  - 8 BPP (256 colors).
**  - 40 MHz input clock.
**  - 2 MB of 50 ns EDO, 2 CAS, 32 ms refresh memory.
**
**                   *** This is sample code only! ***
**  This means:
**	1) Generic C is used. It is assumed pointers can access all
**		relevent memory addresses (this is not always the case in the real
**		world).
**	2)	Register setup is done with discrete writes rather than being
**		table driven. This makes intentions clearer through the use
**		of comments. A real program	would probably store the register
**		settings in an array and loop through the array writing each
**		element to a control register.
