11.2 Instruction Description
1) Display On/Off
The display data appears when D is 1 and disappears when D is 0.
Though the data is not on the screen with D=0, it remains in the display data RAM.
Therefore,you can make it appear by changing D=0 into D=1.

When BUSY is 1, the Chip is executing internal operation and no instructions are
accepted.
When BUSY is 0, the Chip is ready to accept any instructions.
lON/OFF
When ON/OFF is 1, the display is off.
When ON/OFF is 0, the display is on.
lRESET
When RESET is 1, the system is being initialized.In this condition,no instructions
except status read can be accepted.
When RESET is 0, initializing has finished and the system is in the usual operation
condition.

12.Reset and Initializing flow chart
12.1 Reset
The system can be initialized by setting RSTB terminal at low level when turning power on,
receiving instruction from MPU.
When RSTB becomes low, following procedure is occurred.
— Display off
— Display start line register become set by 0. (Z-address 0)
While RSTB is low, No instruction except statusread can be accepted. Therefore, execute
other instructions after making sure that DB4 = 0 (clear RSTB) and DB7 = 0 (ready) by
status read instruction. The Conditions of power supply at initial power up are shown as
follow.
