Sample Applications Circuit 1
1/4 Duty, 1/3 Bias Drive
*4 Connect the S37/OSCI pin to the LCD panel in the internal oscillator operating mode and insert a current protection
resistor Rg(2.2 to 22 k) between the S37/OSCI pin and external clock output pin (external oscillator) in the
external clock operating mode. (See “S37/OSCI Pin Peripheral Circuit”)
Sample Applications Circuit 2
Static Drive
*4 Connect the S37/OSCI pin to the LCD panel in the internal oscillator operating mode and insert a current protection
resistor Rg(2.2 to 22 k) between the S37/OSCI pin and external clock output pin (external oscillator) in the
external clock operating mode. (See “S37/OSCI Pin Peripheral Circuit”)
