This terminal selects the master/slave operation for the S1D15605 Series
chips. Master operation outputs the timing signals that are required for the
LCD display, while slave operation inputs the timing signals required for the
liquid crystal display, synchronizing the liquid crystal display system.
The following is true depending on the M/S and CLS status:
This is the display clock input terminal
The following is true depending on the M/S and CLS status.
When the S1D15605 Series chips are used in master/slave mode, the
various CL terminals must be connected.
This is the liquid crystal alternating current signal I/O terminal.
When the S1D15605 Series chip is used in master/slave mode, the various
FR terminals must be connected.
This is the liquid crystal display blanking control terminal.
When the S1D15605 Series chip is used in master/slave mode, the various
DOF terminals must be connected.
This is the output terminal for the static drive.
This terminal is only enabled when the static indicator display is ON when
in master operation mode, and is used in conjunction with the FR terminal.
This terminal selects the resistors for the V
regulated by an external resistive voltage divider attached to the VR
terminal.
This pin is enabled only when the master operation mode is selected.
It is fixed to either HIGH or LOW when the slave operation mode is selected.
This is the power control terminal for the power supply circuit for liquid
crystal drive.
This pin is enabled only when the master operation mode is selected.
It is fixed to either HIGH or LOW when the slave operation mode is selected.
