Clear Display Memory
1
The display refresh memory is cleared to zero. All positions will display “@” character.
Load Blank to Display
1
The display refresh memory is loaded with the ASCII code for blank (1 0 0 0 0 0 0). All characters will be blank.
Rotate Display Left
1
The display is rotated one place to the left. The most significant character is shifted into the least significant character
position. (Upper left character is shifted to lower right position.)
Rotate Display Right
1
The display is rotated one place to the right. The least significant character position is shifted into the most significant
position. (Lower right character is shifted to upper left position.)
Shift Display Left
1
The display is shifted for one place to the left. The most significant character (upper left) is lost, the last character
(lower right) becomes blank.
Shift Display Right
1
The display is shifted for one place to the right. The last character (lower right) is lost, the most significant character
(upper left) becomes blank.
Increment Cursor
1
The cursor is incremented one position (shifted to the right). The content of the display refresh memory pointed to by
the cursor is placed in the output register.
Decrement Cursor
1
The cursor is decremented one position (shifted to the left). The content of the display refresh memory pointed to by
the cursor is placed in the output register.
Get Key Address
1
The address of the depressed key (6 bits) is loaded into the output register. At the end of this instruction (same as for
every GET instruction), the output register contains data. The CPU will read data by strobing CS, RD an A0 = 0. (bit 7
up) Note that KB IRQ is cleared (set high) and Bit 7 is set low when execution is complete.
Get Display Memory
1
First the cursor is auto-incremented according to the display status work. Then, the content of the display refresh
memory (ASCII) code) pointed to by the cursor is placed into the output register.
