LCD power control output. The active polarity of this output
is selected by the state of MD10 at the rising edge of
RESET# - see Section 5.5,
“Summary of Configuration
Options”
on page 31.

This pin has multiple functions which are automatically
selected depending on panel type used.
• For TFT panels, this is the display enable output
(DRDY).
• For passive LCDs with Format 1 interfaces, this is the
2nd Shift Clock (FPSHIFT2).
• For all other LCD panels, this is the LCD backplane bias
signal (MOD).
