Notes: 1. Fix G and B pins low if CRT display data is monochrome.
2. Fix high or low if the display timing signal is generated internally.
3. For 8-color display modes.
4. For monochrome or 8-level gray-scale display modes.
5. Leave disconnected in 4-bit/single-screen data transfer modes.
6. Leave disconnected in monochrome or 8-level gray-scale display modes.
7. Leave disconnected in TN-type LCD modes.
8. Leave disconnected if no buffer memory is used.
9. Pull up with a resistor of about 20k
in monochrome display modes.
The HD66841 writes the OR of RGB signals into R-plane RAM, so no RAM is required for the G
and B planes in these modes. (If G- or B-plane RAM is connected in monochrome display
modes, the HD66841 writes G or B signals into each RAM. However, this does not affect the
display or the contents of R-plane RAM.)
10.Multiplexed pins.
11.Fix high or low when using the ROM programming method.
12.Fix high or low when using the MPU programming method.
13.Do not set pins
WR
and
RD
low simultaneously.
14.A reset signal must be input after power-on.
