11.Detailed Explanation
Display On/Off
R/W D/I DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
00 0011 111D
The display data appears when D is and disappears when D is 0. Though the data is not
on the screen with D = 0, it remains in the display data RAM. Therefore, you can make it
appear by changing D = 0 into D = 1.
Display Start Line
R/W D/I DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
0 0 1 1 AAAAAA
Z address AAAAAA ( binary ) of the display data RAM is set in the display start line
register and displayed at the top of the screen. Figure 2. shows examples of display ( 1/64 duty
cycle ) when the start line = 0-3. When the display duty cycle is 1/64 or more ( ex. 1/32, 1/24
etc. ), the data of total line number of LCD screen, from the line specified by display start line
instruction, is displayed
Set Page ( X Address )
R/W D/I DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
0 0 1 0 1 1 1 AAA
X address AAA ( binary ) of the display data RAM is set in the X address register. After
that, writing or reading to or from MPU is executed in this specified page until the next page is
set. See Figure 1.
