Instruction Set
Two different instructions formats are provided:
- With D/C set to LOW
commands are sent to the Control circuitry.
- With D/C set to HIGH
the Data RAM is addressed Instructions have the syntax summarized in Table.1.
Reset (RES)
At power-on, all internal registers and RAM content are not defined. A Reset pulse must be applied on RES pad
(active low) to initialize the internal registers content (see Tables 3,4,5,&6). Every on-going communication with
the host controller is interrupted. The IC after the reset pulse is programmed in Power Down mode.
The Default configurations is:
- Horizontal addressing (V = 0)
- Normal instruction set (H = 0)
- Normal display (MX = MY = TRS =BRS = 0)
- MUX 65 mode (MUX = 0)
