XTENDED COMMAND SET
9.1.2.1
Horizontal/vertical addressing
Two different addressing modes are possible with the
extended command set: horizontal addressing mode and
vertical addressing mode.
In the horizontal addressing mode (V = 0) the X address
increments after each byte. After the last X address,
X wraps around to 0 and Y increments to address the next
row (see Fig.4). The number of columns (last X address)
after which the wrap around must occur can be
programmed. In Fig.4 it can be seen that the X address is
programmed to be 127, and the Y address is programmed
tobe 9.WithX maxandY maxtheX andY addressescan
be programmed while the whole RAM is not being used.
In the vertical addressing mode (V = 1) the Y address
increments after each byte. After the last Y address
(Y = 9), Y wraps around to 0 and X increments to address
thenextcolumn(seeFig.5).ThelastY addressafterwhich
Y wraps to 0 can be programmed. In Fig.5 it can be seen
that the X address is programmed to be 127, and the
Y address is programmed to be 9. With X max and Y max
the X and Y addresses can be programmed while the
whole RAM is not being used.
After the very last address the address pointers wrap
around to address X = 0 and Y = 0 in both horizontal and
vertical addressing modes.
