Display start line register is cleared to 0
Column address counter is cleared to 0
Page address is cleared to 0
Normal scan direction of the COM outputs
Internal regulator resistors Ratio is set to 4
Contrast control register is set to 20h
Set End of Read-Modify-Write Mode
This command relieves the chip from read-modify-write mode. The column address before entering read-
modify-write mode will be restored no matter how much modification during the read-modify-write mode.
Set Indicator On/Off
This command turns on or off the static indicator driven by the M and MSTAT pins.
When the “Set Indicator On” command is sent, the second command byte “Indicator Display Mode” must
be followed. However, the “Set Indicator Off” command is a single byte command and no second byte
command is required.
The status of static indicator also controls whether standby mode or sleep mode will be entered, after
issuing the power save compound command. See “Set Power Save Mode” later in this section.
NOP
A command causing the chip takes No Operation.
Set Test Mode
This command forces the driver chip into its test mode for internal testing of the chip. Under normal
operation, users should NOT use this command.
Set Power Save Mode
Entering Standby or Sleep Mode should be done by using a compound command composed of “Set
Display ON/OFF” and “Set Entire Display ON/OFF” commands. When “Set Entire Display ON” is issued
when display is OFF, either Standby Mode or Sleep Mode will be entered.
The status of the Static Indicator will determine which power save mode is entered. If static indicator is off,
the Sleep Mode will be entered:
Internal oscillator and LCD power supply circuits are stopped
Segment and Common drivers output V
DD
level
The display data and operation mode before sleep are held
Internal display RAM can still be accessed
If the static indicator is on, the chip enters Standby Mode, which is similar to sleep mode except addition
with:
Internal oscillator is on
Static drive system is on
Please also be noted that during Standby Mode, if the software-reset command is issued, Sleep Mode
will be entered. Both power-save modes can be exited by the issue of a new software command or by
pulling Low at hardware pin
RES
.
Status register Read
This command is issued by pulling
D/
C
Low during a data read (refer to Figure 9 on Page 38 and Figure
10 on Page 39 for parallel interface waveforms). It allows the MCU to monitor the internal status of the
chip.
No status read is provided for serial mode.
