Write RAM Command (5Ch)
After this single byte command, data entries will be written into the display RAM until another command is
written. Address pointer is increased accordingly. This command must be sent before write data into
RAM.
Read RAM Command (5Dh)
After this single byte command, data is read from display RAM until another command is written. Address
pointer is increased accordingly. This command must be sent before read data from RAM.
Set Re-map & Color Depth (A0h)
This command has multiple configurations and each bit setting is described as follows.
Address increment mode (A[0])
When it is set to 0, the driver is set as horizontal address increment mode. After the display RAM
is read/written, the column address pointer is increased automatically by 1. If the column address
pointer reaches column end address, the column address pointer is reset to column start address
and row address pointer is increased by 1. The sequence of movement of the row and column
address point for horizontal address increment mode is shown in Figure 21.

Figure 21 – Address pointer movement of horizontal address increment mode
When A[0] is set to 1, the driver is set to vertical address increment mode. After the display RAM
is read/written, the row address pointer is increased automatically by 1. if the row address pointer
reaches the row end address, the row address pointer is reset to row start address and column
address pointer is increased by 1. The sequence of movement of the row and column address
point for vertical address increment mode is shown in Figure 22.

Column Address Mapping (A[1])
This command bit is made for flexible layout of segment signals in OLED module with segment
arranged from left to right or vice versa.
Color Remap (A[2])
This command bit is made for flexible layout of color sequence A
