 * $Log: cs8900.h,v $
 * Revision 1.1  2005/07/26 18:02:27  haraldkipp
 * Moved from dev.
 *
 * Revision 1.2  2004/05/25 11:39:48  olereinhardt
 * Define NUT_CS8900_OLD to get the old functionality back again
 *
 * Revision 1.1  2004/05/24 17:09:17  olereinhardt
 * Changed base address handling in cs8900.c and moved cs8900.h to /include/dev
 * Base address can now be passed to the nic driver by NutRegisterDevice.
 * Removed some Assembler code in cs8900.c
 *
 * Added some databus waitstate settings for the upper half of the address space in os/arch/avr_nutinit.c. Now three waitstates are default for 0x8000-0xFFFF
 *
 * Added terminal device driver for hd44780 compatible LCD displays directly
 * connected to the memory bus (memory mapped). See hd44780.c for more information.
 * Therefore some minor changed in include/dev/term.h and dev/term.c are needet to
 * pass a base address to the lcd driver.
 *
 * Revision 1.1  2003/07/20 16:37:21  haraldkipp
 * CrystalTek 8900A driver added.

 * Revision 1.0  2002/10/1 MJC CDCS
