9. COMMAND DESCRIPTIONS
Set Column Address (15h)
This 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.
Set Row Address (75h)
This 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.
For example, column start address is set to 2 and column end address is set to 129, row start address is
set to 1 and row end address is set to 130. 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 129
and from row 1 to row 130 only. In addition, the column address pointer is set to 2 and row address
pointer is set to 1.
automatically by 1 to access the next RAM location for next read/write operation. Whenever the column
address pointer finishes accessing the end column 129, it is reset back to column 2 and row address is
automatically increased by 1. While the end row 130 and end column 129 RAM location is accessed, the
row address is reset back to 1. The diagram below shows the way of column and row address pointer
movement for this example.
