Out Output Even Data[23:0] corresponds to 24-bit pixel data for one pixel per clock input mode
and to the first 24-bit pixel data for two pixels per clock mode.
Output data is synchronized with output data clock (ODCK).
Refer to the TFT Panel Data Mapping section, which tabulates the relationship between the
input data to the transmitter and output data from the receiver.
A low level on PD# or PDO# will put the output drivers into a high impedance (tri-state) mode.
A weak internal pull-down device brings each output to ground.

Diagram
Out Output Odd Data[23:0] corresponds to the second 24-bit pixel data for two pixels per clock
mode. During one pixel per clock mode, these outputs are driven low.
Output data is synchronized with output data clock (ODCK).
Refer to the TFT Panel Data Mapping section, which tabulates the relationship between the
input data to the transmitter and output data from the receiver.
A low level on PD# or PDO# will put the output drivers into a high impedance (tri-state) mode.
A weak internal pull-down device brings each output to ground.
ODCK 44 Out Output Data Clock. This output can be inverted using the OCK_INV pin. A low level on PD# or
PDO# will put the output driver into a high impedance (tri-state) mode. A weak internal pull-
down device brings the output to ground.
DE 46 Out Output Data Enable. This signal qualifies the active data area. A HIGH level signifies active
display time and a LOW level signifies blanking time. This output signal is synchronized with
the output data. A low level on PD# or PDO# will put the output driver into a high impedance
(tri-state) mode. A weak internal pull-down device brings the output to ground.

General output control signal 1. This output is not powered down by PDO#.
General output control signal 2.
General output control signal 3.
A low level on PD# or PDO# will put the output drivers (except CTL1 by PDO#) into a high
impedance (tri-state) mode. A weak internal pull-down device brings each output to ground.
