8. Display Screen and Initialize Set
The Display screen consists of 4,096 dots arranged as 128 by 32 dots. It is divided into 32 display area blocks of 16 by
8 dots each. Each display area block can be assigned to GRAM (Graphic mode) or DDRAM (Character mode) by the
Display Area Set command. (9.5 Page #10)
But, this is the version which has no Font ROM. Therefore, DDRAM is not available, all of display area block must
be assigned to GRAM as the initialize setting, and this must be done when the module is powered up and also
every time the reset is applied, because all display area blocks are set to DDRAM area as default setting.
Initialize sequence is as follows;
NO
C/D=1 0nHex
Initialize Set Start
C/D=1 5FHex
C/D=1 62Hex
C/D=0 FFHex
