Instructions
Outline
The MOP-GL24064A is controlled using a standard T6963 compliant controller. The display is enabled by
pulling the Chip Select (CS) pin low, communication to and from the device is controlled using the active
low Write (WR) and Read (RD) inputs, and the unit may be reset by pulling the RST line low. Using
Register Select, either the Command Register (C) or Data Register (D) is selected by toggling C/D high or
low respectively.
Before any data is read or written, the status of the display controller must be read. This is
accomplished by setting RD low, WR high, CS low, C/D high, and reading the status byte that appears on
the data lines. Each bit of the status word indicates a specific condition, outlined below.

The first two bits, D0 and D1, should be read at the same time. In auto mode, D2 and D3 become valid
while D0 and D1 are invalid. The display should be in an enabled condition before commands or data
are transmitted. Data bytes are transferred before commands, as shown below.
