STANDARD
NAME
6.2.2 Cursor Home
6.2.3 Entry Mode Set
This instruction
(1) Clears the contents of the address counter (ACC) to 00H.
(2) Sets the address counter (ACC) to point to the DD-RAM.
(3) Sets the display for zero character shift (returns original position).
(4) If the cursor is displayed, moves the left most character in the top line (upper line).
I/D=1: The address counter (ACC) is incremented.
I/D=0: The address counter (ACC) is decremented.
The S bit enable display shift, instead of cursor shift , after each write or read to the DD-RAM.
The direction in which the display is shifted is opposite in sense to that of the cursor.
For example, if S=0 and I/D=1, the cursor would shift one character to the right after a MPU writes to
DD-RAM. However if S=1 and I/D=1, the display would shift one character to the left and the cursor would
maintain its position on panel.
The cursor will already be shifted in the direction selected by I/D during reads of the DD-RAM,
irrespective of the value of S. Similarly reading and writing the CG-RAM always shift the cursor.
Also both lines are shifted simultaneously.
The I/D bit selects the way in which the contents of the address counter (ACC) are modified after every
access to DD-RAM or CG-RAM.
