/*
* 86Box A hypervisor and IBM PC system emulator that specializes in
* running old operating systems and software designed for IBM
* PC systems and compatibles from 1981 through fairly recent
* system designs based on the PCI bus.
*
* This file is part of the 86Box distribution.
*
* Trident TGUI9400CXi and TGUI9440/96x0 emulation.
*
* TGUI9400CXi has extended write modes, controlled by extended
* GDC registers :
*
* GDC[0x10] - Control
* bit 0 - pixel width (1 = 16 bit, 0 = 8 bit)
* bit 1 - mono->colour expansion (1 = enabled,
* 0 = disabled)
* bit 2 - mono->colour expansion transparency
* (1 = transparent, 0 = opaque)
* bit 3 - extended latch copy
* GDC[0x11] - Background colour (low byte)
* GDC[0x12] - Background colour (high byte)
* GDC[0x14] - Foreground colour (low byte)
* GDC[0x15] - Foreground colour (high byte)
* GDC[0x17] - Write mask (low byte)
* GDC[0x18] - Write mask (high byte)
*
* Mono->colour expansion will expand written data 8:1 to 8/16
* consecutive bytes.
* MSB is processed first. On word writes, low byte is processed
* first. 1 bits write foreground colour, 0 bits write background
* colour unless transparency is enabled.
* If the relevant bit is clear in the write mask then the data
* is not written.
*
* With 16-bit pixel width, each bit still expands to one byte,
* so the TGUI driver doubles up monochrome data.
*
* While there is room in the register map for three byte colours,
* I don't believe 24-bit colour is supported. The TGUI9440
* blitter has the same limitation.
*
* I don't think double word writes are supported.
*
* Extended latch copy uses an internal 16 byte latch. Reads load
* the latch, writing writes out 16 bytes. I don't think the
* access size or host data has any affect, but the Windows 3.1
* driver always reads bytes and write words of 0xffff.
