13. Resistance between terminal X and terminal V (one of V1L, V1R, V2L, V2R, V5L, V5R, V6L,
and V6R) when load current flows through one of the terminals X1 to X64. This value is
specified under the following conditions:
V_CC–V_EE = 10V
V1L = V1R, V6L = V6R = V_CC – 1/7 (V_CC–V_EE)
V2L = V2R, V5L = V5R = V_EE + 1/7 (V_CC–V_EE)

The following is a description of the range of power supply voltage for liquid crystal display
drive. Apply positive voltage to V1L = V1R and V6L = V6R and negative voltage to V2L = V2R
and V5L = V5R within the ÆV range. This range allows stable impedance on driver output
(RON). Notice that ÆV depends on power supply voltage V_CC–V_EE.
