Terminal
OSC1

name

FR
A terminal for connecting a resistor for internal oscillation.
When M/S = 0, internal oscillation is prohibited, making OCS2 serve as a clock input
terminal in the opposite phase to OCS1. During the power-saving mode, oscillation and
clock input are prohibited, making OCS2 work as a high-impedance terminal. (See the
explanation of functions.)
Input/output terminal
An input/output terminal for AC control signals for the LCD panel.
M/S = 1: Output
M/S = 0: Input
Output for driving the LCD segments. Depending on the combination of the FR signal
and the contents of the display RAM, one of the V

They are common (LOW) output terminals for driving the LCD panel. Depending on the

Input
A terminal that selects whether the MPU operates as a master or slave of the S1D15400.
It connects to V
OSC2 terminals.
M/S = V
* When the FR signal is used to establish synchronization between the master and slave
ICs, both of them will output the same waveforms from the COM terminal.
