DV_DD18
Pixel clock input used to load image data into the CCD controller (CCDC) on pins
CI[7:0] and YI[7:0].
Vertical synchronization signal that can be either an input (slave mode) or an output
(master mode), which signals the start of a new frame to the CCDC.
Horizontal synchronization signal that can be either an input (slave mode) or an
output (master mode), which signals the start of a new line to the CCDC.
This pin is multiplexed between the CCDC and UART2.
When used by the CCDC as input CI7, it supports several modes.
In 16-bit CCD analog-front-end (AFE) mode, it is input CCD15.
In 16-bit YCbCr mode, it is time multiplexed between CB7 and CR7 inputs.
In 8-bit YCbCr mode, it is time multiplexed between Y7, CB7, and CR7 of the upper
8-bit channel.

(1) I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal
(2) IPD = internal pulldown, IPU = internal pullup. (To pull up a signal to the opposite supply rail, a 1-kΩ resistor should be used.)
(3) Specifies the operating I/O supply voltage for each signal
