Two-color display character Attribute Table. The attributes for two-color display characters may be written or read via the following
address format:
A15–A6: Always 1000_0100_01b.
A5–A2: Attribute code (0h-Fh are valid values), n
A1–A0: Determines which of the 3 bytes is to be accessed.
NOTE: In the table, n indicates the attribute number 0<=n< =15
NOTE: When writing, bytes 0 through 2 must be written, in that order. Bytes 0 through 2 will take effect after byte 2 is written.
Since byte 3 contains all reserved bits, this byte may be written, but no effect will result.
When reading, it is OK to read only one, two, or all three bytes.
If writing more than one 2-color attributes using the auto increment feature, all four bytes must be written.
