File : LCDLin.C
Purpose : Driver for LCDs using a single Seiko Epson SED13XX controllers
This version supports a single LCD controller
in (almost) any hardware configuration. The following
derivatives are currently supported:
SED1352
SED1354
SED1356 (With/Without BitBlt engine support)
SED1374
SED1375
SED13806
Other Epson LCD controllers are very similar and could
be covered by this driver as well, but have not been
tested.

---------------------------LIST OF CONFIG SWITCHES--------------------
The following is a list of additional configuration switches for this
driver. These switches might not be listed in the manual, because
the manual mainly covers the general config switches which are
supported by all drivers.
----------------------------------------------------------------------
define ----------------------Explanation------------------------------
LCD_SWAP_BYTE_ORDER Activate if high low bytes are swapped
Default: 0
LCD_WRITE_MEM32(Off,Data32) This macro accelerates display access
if defined by allowing the CPU to write
32 bits at a time to the controller.
(For 32 bits CPUs only and only if the
BUS interface unit can automatically
convert this to 2 16 bit accesses
LCD_OPTIMIZE Controls the use of optimized routines.
If 1, several (speed) optimizations are used.
Default: ON (1)
LCD_USE_BITBLT This switch controls the use of optimized routines
with SED1356 bitblt engine.
If 1, the optimized routines with bitblt access are used.
The default value depends of LCD_BITSPERPIXEL: (4 ) -> 0, (8,15) -> 1
LCD_ENABLE_REG_ACCESS()
LCD_ENABLE_MEM_ACCESS() In most systems (and with most LCD-controllers)
registers / memory can be accessed at
different addresses. However, in some
systems, it could be necessary to exec
code in order to be able to access the
registers or memory. This code should
then be placed in these macros (rather
than the actual access macros, which
would be slowed down)
LCD_DATAADR define adress if video memory can be treated
like regular memory
(will speed up driver)
LCD_USE_32BIT_OFF required if a 16 bit CPU has to control more
video memory than can be handled with 16 bit offsets.
Forces 32 bit computations, which will make driver
bigger & slower.
LCD_COPY_MEM16(Dest, pSrc, NumItems) This macro defines a routine which is used
when displaying device dependend 8bpp bitmaps using a 16 bit bus.
It should copy 16 bit items and return 0 if successfull
and a value != 0 if it fails.
Parameter:
Dest - Destination address
pSrc - Void pointer to source data
NumItems - Number of 16 bit items to be copied
LCD_COPY_MEM16_THRESHOLD Used to decide if the function defined by the macro
LCD_COPY_MEM16 should be used to copy the bitmap data.
It defines the minimum number of bytes to be copied
