Display clock input / output pin
I/O When the S6B0718 is used in master/slave mode (Multi-chip), the CL pins must be
connected each other.
Display sync input / output pin
I/O When the S6B0718 is used in master/slave mode (Multi-chip), the SYNC pins must be
connected each other.
LCD AC signals input / output pin
I/O When the S6B0718 is used in master/slave mode (Multi-chip), the M pins must be
connected each other.
O
Static driver common output pin
This pin is used together with the FRS pin.
O
Static driver segment output pin
This pin is used together with the FR pin.
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
VR pin and external resistive divider control V0 voltage.
Power control pin of the power supplies circuit for LCD driver
I
− HPMB = "L": high power mode
− HPMB = "H": normal mode
This pin is valid in master operation.
