bit 7
EL Panel Mode Enable
When this bit = 1, the EL Panel support circuit is enabled.
When this bit = 0, there is no hardware effect.
This bit enables the S1D13506 built-in circuit for EL panels which require the Frame Rate
Modulation (FRM) to remain static for one frame after every 262143 frames (approxi-
mately 1 hour at 60Hz refresh). When this bit is enabled, the need for external circuitry to
perform the above function is eliminated.
