S1D1530
S1D15300 series master/slave mode select input. When a necessary
signal is output to the LCD, the master operation is synchronized with
the LCD system, while when a necessary signal is input to the LCD,
the slave operation is synchronized with the LCD system.
The folLOWing is provided depending on the M/S status.
Display clock input/output. When the S1D15300 series selects master/
slave mode, each CL pin is connected. When it is used in
combination with the common driver, this input/output is connected to
common driver YSCL pin.
LCD AC signal input/output. When the S1D15300 series selects master/
slave mode, each FR pin is connected.
When the S1D15300 series selects master mode this input/output is
connected to the common driver FR pin.
Common drive signal output. This output is enabled for only at master
operation and connects to the common driver DIO pin. It becomes HZ
at slave operation.
Test pin. Don’t connect.
LCD blanking control input/output. When the S1D15300 series selects
master/slave mode, the respective DOF pin is connected. When it
is used in combination with the common driver (S1D16305), this output/
input is connected to the common driver DOFF pin.
Static drive output.
This is enabled only at master operation and used together with the FR
pin. This output becomes HZ at slave operation.
• Write enable input. When interfacing to an 8080-series microprocessor,
• When interfacing to an 6800-series microprocessor,
Microprocessor interface select terminal.
Serial data input/parallel data input select pin.
* In serial mode, no data can be read from RAM.

WR is active LOW.
it will be read mode when R/W is HIGH and it will be write mode when
R/W is LOW.

C86 = HIGH: 6800 series microprocessor interface
C86 = LOW: 8080 series microprocessor interface
When P/S = LOW, D0 to D5 are HZ and RD and WR must be fixed HIGH
or LOW.
