In the Black & white mode, the MSBs of 4 bit corresponding with RGB are used to display data.
And so, 128x162 dot gray display or 384
162 B/W mode display is possible.
Display RAM is accessed with X address and Y address from CPU by 8 bit or 16 bit unit.
X address and Y address can be increased automatically by setting status of control register.
The address is increased per every read and write of display RAM by CPU. ( Please see detail
description at command function.)
X direction is selected by X address and Y direction is selected by Y address. Please do not set the
address on non-effective area and it is forbidden to set address on outside area in each case.
384bit display data of Y direction are read out to display latch at rising edge of CL signal per 1 line
cycle and this data comes out from display latch at falling edge of CL signal.
Display start line address register is preset to line counter at “H” state of FLM signal which changes
per one frame cycle and the address is counted up with synchronized CL input.
Display line address counter is synchronized by timing signals of LCD driver, and it operates
independently with X, Y address counters.
(7) Window address assign of display RAM
This IC can be accessed to display RAM by window area designation in addition to access to
display RAM designated by X and Y address.
Through address space of all display address, specific area of RAM can be accessed by designated
two points.
The start point of two point addresses is assigned by normal X address and Y address register and
the end point of them is done by X end address and Y end address register value. Designated
inner addresses depend on WLS bit.
Read modified write action can be taken by AIM=“1”.
In case of using window area accessing mode, you must set start point X address, Y address in
sequence and end point X address, Y address in sequence after executing Win command (WIN=“1”,
auto increase mode AXI=“1”, AYI=“1”) and then access to Display RAM.
And set start point and end point not to be designated to access the outside of available address
area. Address set value should be taken to set AX
≤
EX ( end point of X address ) and AY
≤
EY
( end point of Y address ).
X direction
