Chip Select
This is the chip select input. The chip is enable for MCU
communication only when CS# is pulled low.
Power Reset for Controller and Drive
This is reset signal input. When the pin is low, initialization of the chip
is executed.
Data/ Command Control
This pin is Data/Command control pin. When the pin is pulled high, the
input at D0~D7 is treated as display data. When the pin is pulled low,
the input at D0~D7 will be transferred to the command register.
Write or Read/Write Select
When 80xx interface mode is selected, the pin will be the Write (WR#)
input.
When interfacing to a 68xx-series microprocessor, the 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.
Read or Read/Write Enable
When 80xx interface mode is selected, the pin will be the Read (RD#)
input.
When interfacing to a 68xx-series microprocessor, the 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.

Note1烉All the above voltages are on the basis of “VSS=0V”
Note2烉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 6 “Electrical
Characteristics”. If this module is used beyond these conditions, malfunctioning of the
module can occur and the reliability of the module may deteriorate.

FUNCTION SPECIFICATION
1.
Commands
Refer to the Technical Manual for the SEPS114A
2.
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.
