bit 7
EL Panel Mode Enable
When this bit = 1, EL Panel support mode is enabled. Every 262143 frames (approximately 1 hour
at 60Hz frame rate) the identical panel data is sent to two consecutive frames, i.e. the frame rate
modulation circuitry is frozen for one frame.
bits 5-4
Panel Data Width Bits [1:0]
These bits select the LCD interface data width as shown in the following table.
bit 3
Panel Data Format Select
When this bit = 1, color passive LCD panel data format 2 is selected.
When this bit = 0, passive LCD panel data format 1 is selected.
bit 2
Color/Mono Panel Select
When this bit = 1, color passive LCD panel is selected.
When this bit = 0, monochrome passive LCD panel is selected.
bit 1

When this bit = 1, dual passive LCD panel is selected.
When this bit = 0, single passive LCD panel is selected.
bit 0
TFT/Passive LCD Panel Select
When this bit = 1, TFT/D-TFD panel is selected.
When this bit = 0, passive LCD panel is selected.
bits 5-0
MOD Rate Bits [5:0]
When the DRDY pin is configured as MOD, this register controls the toggle rate of the MOD out-
put. When this register is zero, the MOD output signal toggles every FPFRAME. When this register
