13. RCOM is the resistance between the power supply pins (V_CC, V1, V4, V5) and each common signal pin
(COM0 to COM25/COM53).
RSEG is the resistance between the power supply pins (V_CC, V2, V3, V5) and each segment signal pin
(SEG1 to SEG71/SEG119).
14. The following graphs show the relationship between operation frequency and current consumption
(referential data).

15. Applies to the OSC1 pin.
16. Each COM and SEG output voltage is within ±0.15V of the LCD voltage (V_CC, V1, V2, V3, V4, V5)
when there is no load.
17. The TEST pin must be fixed to ground, and the IM pin must also be connected to V_CC or ground.
