LH155BA
2.23. Initialization
The LH155BA is initialized by setting RESB pin to "L".
Normally, RESB pin is initialized together with MPU
by connecting to the reset pin of MPU.
When power is ON, be sure to reset operation.
3. PRECAUTIONS
Precautions when connecting or disconnecting
the power supply
This IC may be permanently damaged by a high
current which may flow if voltage is supplied to the
LCD drive power supply while the logic system
power supply is floating. The details are as follows.

When using the internal power supply
When connecting the power supply
After connecting the logic system power supply,
make reset operation and then execute PON
command.
When disconnecting the power supply
After executing HALT command, disconnect the
logic system power supply.
It is advisable to connect the serial resistor (50 to
