Display Page RAM
(Continued)
Notes:
Every row must begin with an attribute and a SL value.
Display Page RAM memory location 8000h will always be
associated with the SL of row 0 of Display Window #1.
If an I
2
C transmission finishes without an RE (in the
middle of a row) the first byte sent in the next I
2
C trans-
mission is the attribute.
Every row except the last row of a Display Window must
end with an RE character. The character immediately af-
ter an RE character is always the SL value for the next
row.
The last row in a Display Window must be a WE charac-
ter. The WE character must NOT be preceded by an RE
character.
The data shown in Table 10is sent to the LM1253Ain five
