10 COMMAND DESCRIPTIONS
10.1 Set Column Address (15h)
This triple byte command specifies column start address and end address of the display data RAM. This
command also sets the column address pointer to column start address. This pointer is used to define the
current read/write column address in graphic display data RAM. If horizontal address increment mode is
enabled by command A0h, after finishing read/write one column data, it is incremented automatically to the
next column address. Whenever the column address pointer finishes accessing the end column address, it is
reset back to start column address and the row address is incremented to the next row.
10.2 Set Row Address (75h)
This triple byte command specifies row start address and end address of the display data RAM. This
command also sets the row address pointer to row start address. This pointer is used to define the current
read/write row address in graphic display data RAM. If vertical address increment mode is enabled by
command A0h, after finishing read/write one row data, it is incremented automatically to the next row address.
Whenever the row address pointer finishes accessing the end row address, it is reset back to start row address.
The diagram below shows the way of column and row address pointer movement though the example:
column start address is set to 2 and column end address is set to 125, row start address is set to 1 and row end
address is set to 126; Horizontal address increment mode is enabled by command A0h. In this case, the
graphic display data RAM column accessible range is from column 2 to column 125 and from row 1 to row
126 only. In addition, the column address pointer is set to 2 and row address pointer is set to 1. After
finishing read/write one pixel of data, the column address is increased automatically by 1 to access the next
RAM location for next read/write operation (solid line in Figure 10-1). Whenever the column address pointer
finishes accessing the end column 125, it is reset back to column 2 and row address is automatically increased
by 1 (solid line in Figure 10-1). While the end row 126 and end column 125 RAM location is accessed, the
row address is reset back to 1 and the column address is reset back to 2 (dotted line in Figure 10-1). .
