I

− CLS = “H”: enable

− CLS = “L”: disable (external display clock input to CL pin)

Display clock input / output pin

I/O When the S6B0721 is used in master/slave mode (multi-chip), the CL pins must be

connected each other.

LCD AC signal input / output pin

When the S6B0721 is used in master/slave mode (multi-chip), the M pins must be

I/O connected each other.

− MS = “H”: output

− MS = “L”: input

O

Static driver segment output pin

This pin is used together with the M pin.

LCD display blanking control input / output

When S6B0721 is used in master/slave mode (multi-chip), the DISP pins must be

I/O connected each other.

− MS = “H”: output

− MS = “L”: input

Internal resistors select pin

This pin selects the resistors for adjusting V0 voltage level.

I

− INTRS = "H": use the internal resistors.

− INTRS = "L": use the external resistors.

V0 voltage is controlled with VR pin and external resistive divider.

Power control pin of the power supply circuit for LCD driver

I

− HPM = "H": high power mode

− HPM = "L": normal mode

This pin is valid in master operation.
