2.4.2
In addition to the VGA pass-through mode, there are four multiplexing modes available, all of which are
referred to as normal modes. In each normal mode, a pixel bus width of 8, 16, or 32 bits may be used. Modes
1, 2, and 3 also support a pixel bus width of 4 bits. Data should always be presented on the least significant
bits of the pixel bus. For example, when a 16-bit-wide pixel bus is used and there are 8 bits per pixel, each
8-bit pixel should be presented on P<0:7>. All the unused pixel bus pins should be connected to GND.
Multiplexing Modes
Mode 1 uses a single bit plane to address the color palette. The pixel port bit is fed into bit 0 of the palette
address, with the 7 high-order address bits being defined by the palette page register (see Section 2.2.3).
This mode has uses in high-resolution monochrome applications such as desktop publishing. This mode
allows the maximum amount of multiplexing (a 32:1 ratio), thus giving a pixel bus rate of only 4 MHz at a
screen resolution of 1280 by 1024. Although only a single bit plane is used, alteration of the palette page
register at the line frequency allows 256 different colors to be displayed simultaneously with 2 colors per
line.
Mode 2 uses 2 bit planes to address the color palette. The 2 bits are fed into the low-order address bits of
the palette with the 6 high-order address bits being defined by the palette page register (see Section 2.2.3).
This mode allows a maximum divide ratio of 16:1 on the pixel bus and is a 4-color alternative to mode 1.
Mode 3 uses 4 bit planes to address the color palette. The 4 bits are fed into the low-order address bits of
the palette with the 4 high-order address bits being defined by the palette page register (see Section 2.2.3).
This mode provides 16 pages of 16 colors and can be used at SCLK divide ratios of 1 to 8.
Mode 4 uses 8 bit planes to address the color palette. Since all 8 bits of palette address are specified from
the pixel port, the page register is not used. This mode allows dot-clock-to-SCLK ratios of 1:1 (8-bit bus),
2:1 (16-bit bus) or 4:1 (32-bit bus). Therefore, in a 32-bit configuration, a 1024-by-768 pixel screen can be
implemented with an external data rate of only 16 MHz.
All Normal multiplexing modes can support Little Endian (default) and Big Endian data formats at the pixel
bus inputs (see section 2.6.1).
2.4.3
Special-Nibble Mode
Mode 5 is special nibble mode, which is enabled when the general control register SNM bit (bit 3) is set to
1 and the general control register SSRT bit (bit 2) is set to 0 (see Section 2.11). When special-nibble mode
is enabled, it takes precedence over the other modes, and the mux control register setup is ignored. The
SFLAG/NFLAG input is then used as a nibble flag to indicate which nibble of each byte holds the pixel data.
Special-nibble mode is a variation of the 4-bit pixel mode with a 16-bit pixel width. All 32 inputs (P0 through
P31) are connected as 4 bytes, but the 16-bit data bus is composed of either the lower or upper nibble of
each of the 4 bytes. For more detailed information, refer to Section 2.9.2. Since this mode uses 4 bit planes
for each pixel, they are fed into the low-order address bits of the palette, with the 4 high-order address bits
being defined by the palette page register (see Section 2.2.3).
2.4.4
True-Color Modes
Mode 6 is the true-color mode in which 24, 16, or 15 bits of data are transferred from the pixel port directly
to the DACs, but with the same amount of pipeline delay as the overlay data and the control signals (BLANK
and SYNCs). Depending on which true-color mode is selected, overlay is provided by utillizing the remaining
bits of the pixel bus to address the palette RAM (refer to Tables 2–6 and 2–7). This results in a 24-bit RAM
output that is then used as overlay information to the DACs. When all of the overlay inputs are at logic 0,
no overlay information is displayed. When a non-zero value is input, the color palette RAM is addressed and
the resulting data is then fed through to the DACs and receives priority over the true-color data.
Mode 6a is the TARGA compatible (5-5-5) true-color mode. In this 16-bit mode, there are 5 bits of RED, 5
bits of GREEN, 5 bits of BLUE, and an additional overlay bit. Refer to Table 2–8 for the exact bit definitions.
Mode 6b is the XGA compatible (5-6-5) true-color mode. This 16-bit mode has 5 bits of RED, 6 bits of
GREEN, and 5 bits of BLUE data. The overlay function is not enabled in this mode. Refer to Table 2–8 for
the exact bit definitions.
