When the ML9050/9051 is used in the master/slave mode, the
corresponding CL pin has to be connected.
FR

I/O
This is the input/output pin for LCD display frame reversal signal.
M/S = "H": Output
M/S = "L": Input
When the ML9050/9051 is used in the master/slave mode, the
corresponding FR pin has to be connected.
DOF

I/O
This is the blanking control pin for the LCD display.
M/S = "H": Output
M/S = "L": Input
When the ML9050/9051 is used in the master/slave mode, the
corresponding
DOF
pin has to be connected.

I
This is the output pin for static drive.
This pin is used in combination with the FR pin.
This is the pin for selecting the resistor for adjusting the voltage V1.
IRS = "H": The internal resistor is used.
IRS = "L": The internal resistor is not used. The voltage V1 is adjusted
using the external potential divider resistors connected to the pins VR.
This pin is effective only in the master operation. This pin is tied to the
"H" or the "L" level during slave operation.
HPM

I
This is the power control pin for the LCD drive power supply circuit.
HPM
= "H": Normal mode
HPM
= "L": High power mode
This pin is effective only during master operation mode. This pin is tied to
the "H" or the "L" level during slave operation.
