ALTERNATE COLOR / DATA MAPPING
Color Mapped data Pin names are provided to specify a rec-
ommended mapping for 24-bit Color Applications. Seven [7]
is assumed to be the MSB, and Zero [0] is assumed to be the
LSB. While this is recommended it is not required. When con-
necting to earlier generations of FPD-Link II Ser and Des
devices, a color mapping review is recommended to ensure
the correct connectivity is obtained. Table 16 provides exam-
ples for interfacing to 18-bit applications with or without the
video control signals embedded. The DS90UR906Q Des also
provides additional flexibility with the MAP_SEL feature as
well.

Scenario 3
Scenario 3
Scenario 3 supports an 18-bit RGB color mapping, 3 un-em-
bedded video control signals, and up to three general purpose
signals.
Scenario 2
Scenario 2 supports an 18-bit RGB color mapping, 3 embed-
ded video control signals, and up to six general purpose
signals.
Scenario 1
Scenario 1 supports the 24-bit RGB color mapping, along with
the 3 embedded video control signals. This is the native mode
for the chipset.
