Master / slave mode select input
Master makes some signals for display, and slave gets them. This is for display
synchronization.
The following table depends on the MS status.
Built-in oscillator circuit enable / disable select pin
Display clock input / output pin
When the S6B0724 is used in master/slave mode (multi-chip), the CL pins must be
connected each other.
LCD AC Signal input / output pin
When the S6B0724 is used in master/slave mode (multi-chip), the M pins must be
connected each other.
Static driver segment output pin
This pin is used together with the FR pin.
Static driver common output pin
This pin is used together with the FRS pin.
LCD display blanking control input / output
When S6B0724 is used in master / slave mode (multi-chip), the DISP pins must be
connected each other.
Internal resistor select pin
This pin selects the resistors for adjusting V0 voltage level and is valid only in master
operation.
V0 voltage is controlled by VR pin and external resistive divider.
