**Chip Select**
This pin is the chip select input. The chip is enabled for MCU communication
only when CS# is pulled low.
**Power Reset for Controller and Driver**
This pin is reset signal input. When the pin is low, initialization of the chip is
executed. Keep this pin pull high during normal operation.
**Data/Command Control**
This pin is Data/Command control pin.
When the pin is pulled high, the input at D7~D0 is treated as display data.
When the pin is pulled low, the input at D7~D0 will be transferred to the
command register.
In I2C interface, this pad serves as SA0 to distinguish the different address.
For detail relationship to MCU interface signals, please refer to the Timing
Characteristics Diagrams.
**Read/Write Select or Write**
This pin is MCU interface input.
When interfacing to a 68XX-series microprocessor, this pin will be used as
Read/Write (R/W#) selection input. Pull this pin to “High” for read mode and
pull it to “Low” for write mode.
When 80XX interface mode is selected, this pin will be the Write (WR#) input.
Data write operation is initiated when this pin is pulled low and the CS# is pulled
low.
When serial mode is selected,thispin must be connected to VSS.|

**Read/Write Enable or Read**
This pin is MCU interface input.
When interfacing to a 68XX-series microprocessor, this pin will be used as the
Enable (E) signal. Read/write operation is initiated when this pin is pulled high
and the CS# is pulled low.
When connecting to an 80XX-microprocessor, this pin receives the Read (RD#)
signal. Data read operation is initiated when this pin is pulled low and CS# is
pulled low.
When serial mode is selected, this pin must be connected to VSS.

**Host Data Input/Output Bus**
These pins are 8-bit bi-directional data bus to be connected to 8-bit standard MPU
data bus.
When serial mode is selected, D1 will be the serial data input pad (SI) and D0 will
be the serial clock input pad (SCL). At this time, D2 to D7 are set to high
impedance.
When I2C interface is selected, D1 will be the serial data input pad (SDA) and D0
will be the serial clock input pad (SCL). At this time, D2 to D7 are set to high
impedance.||||

Note 1: All the above voltages are on the basis of “V `SS` = 0V”.
- Note 2: When this module is used beyond the above absolute maximum ratings, permanent breakage of the module may occur. Also, for normal operations, it is desirable to use this module under the conditions according to Section 3. “Optics & Electrical Characteristics”. If this module is used beyond these conditions, malfunctioning of the module can occur and the reliability of the module may deteriorate.
- Note 3: The defined temperature ranges do not include the polarizer. temperature of the polarizer should be 80 ° C.
- Note 4: V `CC` = 12.0V, T `a` = 25°C, 50% Checkerboard. Software configuration follows Section 4.5 Initialization.
- End of lifetime is specified as 50% of initial brightness reached. The average operating lifetime at room temperature is estimated by the accelerated operation at high temperature conditions.

## **`Functional Specification`**
## Commands
Refer to the Technical Manual for the SH1122
## Power down and Power up Sequence
To protect OEL panel and extend the panel life time, the driver IC power up/down routine should include a delay period between high voltage and low voltage power sources during turn on/off. It gives the OEL panel enough time to complete the action of charge and discharge before/after the operation.
Power up Sequence:
1. Power up V `DD`
2. Send Display off command
3. Initialization
4. Clear Screen
5. Power up V `PP`
6. Delay 200ms (When V `PP` is stable)
7. Send Display on command
Power down Sequence:
1. Send Display off command
2. Power down V `PP`
3. Delay 100ms (When V `PP` is reach 0 and panel is completely discharges)
4. Power down V `DD`

**----- End of picture text -----**
## Note 9:
- 1) Since an ESD protection circuit is connected between V `DD` and V `PP` inside the driver IC, V `PP` becomes lower than V `DD` whenever V `PP` is OFF.
- 2) V `PP` should be kept float (disable) when it is OFF.
- 3) Power Pins (V `DD` , V `PP` ) can never be pulled to ground under any circumstance.
- 4) V `DD` should not be power down before V `PP` power down.
## Reset Circuit
When RES# input is low, the chip is initialized with the following status:
1. Display is OFF. Common and Segment are in high impedance state.
2. 256 × 64 Display Mode
3. Normal segment and display data column and row address mapping (SEG0 mapped to column address 00h and COM0 mapped to row address 00h)
4. Shift register data clear in serial interface.
5. Display start line is set at display RAM address 00H
6. Column address counter is set at 0
7. Normal scanning direction of the Common outputs
8. Contrast control register is set at 80H
9. Internal DC-DC is selected.
