9.1.2 Sample code without using 13504HAL API
/*
**===========================================================================
**
INIT13504.C - sample code demonstrating the initialization of the S1D13504.
**
Beta release 2.0 98-10-22
**
**
The code in this example will perform initialization to the following
**
specification:
**
**
- 320 x 240 single 8-bit color passive panel.
**
- 75 Hz frame rate.
**
- 8 BPP (256 colors).
**
- 33 MHz input clock.
**
- 2 MB of 60 ns FPM memory.
**
**
**
This means:
**
1) Generic C is used. I assume that pointers can access the
**
relevant memory addresses (this is not always the case).
**
i.e. using the 13504B00B card on an Intel 16 bit platform will require
**
changes to use a DOS extender to access memory and registers.
**
2) Register setup is done with discreet writes rather than being
**
table driven. This allows for clearer commenting. A real program
**
would probably store the register settings in an array and loop
