areaddressedbytheaddresspointer.Theaddressranges
are:X = 0 to 100 (64H)andY = 0 to 16 (10H).Itshouldbe
noted that only 3 rows are addressed in bank 16.
Addresses outside these ranges are not allowed.
Bit MX (see Table 3) enables or disables horizontal
address space mirroring:
When bit MX = 0, mirroring is disabled. The address
corresponds to Col0 (see Fig.7).
When bit MX = 1, mirroring is enabled and address
X = 0 corresponds to Col0 (see Fig.8). Bit MX
determines how data is written to the RAM. If bit MX is
changed after writing data to the RAM, no change on the
display will be visible.
