22
UV4/SLAEN
O/I
UV4: Digital output UV bus. UV4 used for 16-bit operation for out-
putting chrominance data.
SLAEN: Slave Enable.
23
UV3/ECLKO
O/I
UV3: Digital output UV bus. UV3 used for 16-bit operation for out-
putting chrominance data.
ECKLO: Swap clock output - changes pin 17(FODD) to XCLK out.
24
UV2/QVGA
O/I
UV2: Digital output UV bus. UV2 used for 16-bit operation for out-
putting chrominance data.
QVGA: QVGA format (320x240)
25
UV1/CC656
O/I
UV1: Digital output UV bus. UV1 used for 16-bit operation for out-
putting chrominance data.
CC656: CCIR 656 mode.
26
UV0/GAMDIS
O/I
UV0: Digital output UV bus. UV0 used for 16-bit operation for out-
putting chrominance data.
GAMDIS: Disables Chroma Gamma (RGB).
27, 28
XCLK1, XCLK2
XO, XI
XCLK1 and XCLK2 are the input/output of the on-chip video oscilla-
tor. Nominal crystal clock frequency is 27MHz. If an external clock is
used, input to XCLK1, leave XCLK2 unconnected.
33
PCLK/OUTX2
O/I
PCLK: Pixel clock output. By default, data is updated at the falling
edge of PCLK and is stable at its rising edge. PCLK runs at the pixel
rate in 16-bit bus operations and twice the pixel rate in 8-bit bus
operations
OUTX2: Doubles current output.
34
Y7/CSO
O/I
Y7: Digital output Y bus. In a 16-bit operation, the luminance data is
clocked out of this bus at the rate of one byte per pixel. In 8-bit oper-
ation, the luminance data and the chrominance data is multiplexed
to this bus.
CSO: ID configuation bit for the SCCB slave ID.
35
Y6/CS2
O/I
Y6: Digital output Y bus. In a 16-bit operation, the luminance data is
clocked out of this bus at the rate of one byte per pixel. In 8-bit oper-
ation, the luminance data and the chrominance data is multiplexed
to this bus.
CS2: ID configuation bit for the SCCB slave ID.
36
Y5/SHARP
O/I
Y5: Digital output Y bus. In a 16-bit operation, the luminance data is
clocked out of this bus at the rate of one byte per pixel. In 8-bit oper-
ation, the luminance data and the chrominance data is multiplexed
to this bus.
SHARP: Enable Analog Sharpness.
37
Y4/CS1
O/I
Y4: Digital output Y bus. In a 16-bit operation, the luminance data is
clocked out of this bus at the rate of one byte per pixel. In 8-bit oper-
ation, the luminance data and the chrominance data is multiplexed
to this bus.
CS1: ID configuation bit for the SCCB slave ID.
38
Y3/RAW
O/I
Y3: Digital output Y bus. In a 16-bit operation, the luminance data is
clocked out of this bus at the rate of one byte per pixel. In 8-bit oper-
ation, the luminance data and the chrominance data is multiplexed
to this bus.
RAW: Raw Data.
39
Y2/G2X
O/I
Y2: Digital output Y bus. In a 16-bit operation, the luminance data is
clocked out of this bus at the rate of one byte per pixel. In 8-bit oper-
ation, the luminance data and the chrominance data is multiplexed
to this bus.
G2X: Gain 2X.
