STANDARD NAME:
7.5.1 CLEAR DISPLAY
RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
0000000001
This instruction clears the display (without affecting the contents of CGRAM) by performing the
following:
1) Fills all DDRAM locations with character code 20H (character code for a space).
2) Sets the AC to DDRAM address 00H (i.e. sets cursor position to 00H).
3) Returns the display to the non-shifted position.
4) Sets the I/D bit to 1.
7.5.2 CURSOR HOME
RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
000000001x
x = don’t care
This instruction returns the cursor to the home position (without affecting the contents of
DDRAM or CGRAM) by performing the following:
1) Sets the AC to DDRAM address 00H (i.e. sets cursor position to 00H).
2) Returns the display to the non-shifted position.
7.5.3 ENTRY MODE SET
RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
00000001I/DS
This instruction selects whether the AC (cursor position) increments or decrements after each
DDRAM or CGRAM access and determines the direction the information on the display shifts
after each DDRAM write. The instruction also enables or disables display shifts after each
DDRAM write (information on the display does not shift after a DDRAM read or CGRAM
access). DDRAM, CGRAM, and AC contents are not affected by this instruction.
I/D = 0: The AC decrements after each DDRAM or CGRAM access. If S = 1, the information
on the display shifts to the right by one character position after each DDRAM write.
I/D = 1: The AC increments after each DDRAM or CGRAM access. If S = 1, the information
on the display shifts to the left by one character position after each DDRAM write.
S = 0: The display shift function is disabled.
S = 1: The display shift function is enabled.
