2.4 Pin Functions

The pin functions tables (Table 2-4through 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

2.4.1Image Data Input - Video Processing Front End

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.
