The pin functions tables (Table 2-4 through Table 2-22 ) identify the external signal names, the associated
pin (ball) numbers along with the mechanical package designator, the pin type, whether the pin has any
internal pullup or pulldown resistors, and a functional pin description. For more detailed information on
device configuration, peripheral selection, multiplexed/shared pins, and debugging considerations, see
Section 3 . For the list of all pin in chronological order see Section 2.5
The CCD Controller module in the Video Processing Front End has an external signal interface for image
data input. It supports YUV (YC) inputs as well as Bayer RGB and complementary input signals (I.e.,
image data input).
The definition of the CCD controller data input signals depend on the input mode selected.
• In 16-bit YCbCr mode, the Cb and Cr signals are multiplexed on the Cl signals and the order is
configurable (i.e., Cb first or Cr first).
• In 8-bit YCbCr mode, the Y, Cb, and Cr signals are multiplexed and not only is the order selectable,
but also the half of the bus used.
