FUNCTIONAL DESCRIPTION
Pin Functional Description
SI (Serial Input)
Input pin for inputting serially commands and display data in an 8-bit unit.
"H"=1 and "L"=0.
When CS pin is at “H” level, read-in is executed by the leading edge of
SHT
.
Whether input data is a command or data is determined by selecting a C/
D
level at the
8th leading edge of
SHT
.
The input data is a command if C/
D
="H", and display data if C/
D
="L".
C/
D
(Command/
Data
)
Input pin for determining whether input data for SI pin is a command or display data.
Read-in is executed by the 8th leading edge of
SHT
. The input data is a command if C/
D="H", and display data if C/
D
="L".
SHT
(
Shift Clock
)
Clock input pin for reading-in SI input and C/
D
input.
Read-in is executed by the clock leading edge. Read-in operation is complete with 8
clocks. Maintain this
SHT
pin at "H" when there is no command and data input from the
SI pin. Inputting data during BUSY may cause malfunction.
Valid if CS pin is at "H" level.
SO (Serial Out)
Serial output pin for reading-out BUSY/NON-BUSY and display data. "H"="1" and
"L"="0". If CS pin is at "H" level and Serial out Enable is set with the command, output
is executed.
Otherwise, this pin becomes high impedance. BUSY/NON-BUSY is output when CS
pin is at "H" level. BUSY if "L" and NON-BUSY if "H". It goes BUSY after the 8th leading
edge of
SHT
, then goes NON-BUSY automatically after a certain time.
Display data is output synchronously with the leading edge of
SHT
.
Input instruction SOE/D to set this output to Serial Out Enable or a high impedance state
since the pin status is undefined after the power is applied.
CS (Chip Select)
Chip Select input pin.
"Chip Select ON" if CS pin is at "H" level, and "Chip Select OFF" at "L" level. When "L"
level is input, SO pin becomes open and
SHT
pin becomes equivalent to "H" level inside
of the IC. Moreover, it prevents the input rows of SI, C/
D
and
SHT
pins from current
flowing.
Note: For SI, C/
D
,
SHT
, SO, and CS, refer to "I/O Procedure".
RST
Direct input reset input pin.
By inputting "L" level pulse into
RST
pin, SOE/D, DISP, ABBC1/5, and ABB commands
are set as D0="0". Before turning on the power, be sure to set
RST
pin at "L" level once.
Setting this pin at "L" level during command execution may cause malfunction.
9D/
17D
(1/9Duty/
1/17Duty
)
Duty setting input pin.
1/9duty is set if this pin is at "H" level, and 1/17duty at "L" level. Choice depends on the
type of panel to be used.
If 1/9duty is selected, common outputs C10 to C17 should be set open.
