TWO-COLOR ATTRIBUTE RAM
This RAM is identical to that of the LM1247. Please refer to the LM1247 datasheet for details.
FOUR-COLOR ATTRIBUTE RAM
This RAM is identical to that of the LM1247. Please refer to the LM1247 datasheet for details.
AUTO SIZE AND HI-BRITE REGISTERS
These registers, shown in
Table 13
provide measured values for the Auto size function and control the Hi-Brite function.
Registers 0x8580 — 0x858A are compatible to the LM1246 Auto Size Registers.
Reserved bits are for internal use and
should not be written to, and any value read should be ignored.
