Connecting pins for feedback resistors of the built-in oscillator
When M/S = HIGH: Connect oscillator resistor Rf to the OSC1
and OSC2 pins. The OSC2 pin is used for output of the oscillator
amplifier.
When M/S = LOW: The OSC2 pin is used for input of oscillation
signal. The OSC1 pin should be left open. Fix the CL pin to theV
Display clock input. The line counter increments on the rising edge
reset this LSI by RES pin.
Display clock output. When using the master operation, the clock
signal is output on this pin. Connect CLO to YSCL on the
common driver.
Master/slave select input. Master makes some signals for display,

be connected to each FR pin. Also when the S1D15600/601/602
series isused as the master MPU, this pin must be connected to
the FRpin of the common driver. Output is selected when M/S is
HIGH, and input is selected when M/S is LOW.
Display sync input/output. If the S1D15600/601/602 series MPU’s
