5.2.6. Function set

RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0

Display data RAM can be read or written after this setting.

Code

0 0 0 0 1 DL N F X X

In one-line display (N = 0),

X: Do not care (0 or 1)

(aaaaaaa)2: (00)16 - (4F)16.

DL: It sets interface data length.

DL = 1: Data transferred with 8-bit length (DB7 - 0).

In two-line display (N = 1),

DL = 0: Data transferred with 4-bit length (DB7 - 4).

It requires two times to accomplish data transferring.

(aaaaaaa)2: (00)16 - (27)16 for the first line,

N: It sets the number of the display line.

N = 0: One-line display.

N = 1: Two-line display.

l F: It sets the character font.

tia ly F = 0: 5 x 8 dots character font.

F = 1: 5 x 10 dots character font.

(aaaaaaa)2: (40)16 - (67)16 for the second line.

5.2.9. Read busy flag and address

Code

RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0

0 1 BF a a a a a a a

When BF = 1, it indicates the system is busy now and it will not

accept any instruction until not busy (BF = 0). At the same time,

the content of Address Counter (aaaaaaa)2 is read.

5.2.10. Write data to character generator RAM or

display data RAM

Code

RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0

10dddddddd

plu IN It sets Character Generator RAM Address (aaaaaa)2 to the

n M Address Counter.

Su RT Character Generator RAM data can be read or written after this

setting.

PA 5.2.8. Set display data RAM address

For Code

RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0

001aaaaaaa

It writes data (dddddddd)2 to character generator RAM or display

data RAM.

5.2.11. Read data from character generator RAM or

display data RAM

Code

RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0

11dddddddd

It reads data (dddddddd)2 from character generator RAM or

display data RAM.

It sets Display Data RAM Address (aaaaaaa)2 to the Address
