Can operate as input (power up default) or output, as determined by direction con-
trol bits in PCI MMIO register INT_CTL.
As input, a PCI_INT# pin can be used to receive PCI interrupt requests (normal
PCI use is active low, level sensitive mode, but the VIC can be set to treat these as
positive edge triggered mode). As input, a PCI_INT# pin can also be used as a
general interrupt request pin if not needed for PCI.
As output, the value of a PCI_INT# can be programmed through PCI MMIO regis-
ters to generate interrupts for other PCI masters.
Whenever XIO bus functionality is active, PCI_INTB# is a push-pull CMOS I/O pin.
When the XIO bus is not active and regular PCI bus functionality is activated, then
PCI_INTB# has a PCI compatible open drain output.

I/O
If configured as input (power up default): a positive transition on this incoming video
clock pin samples all other VI_DATA input signals below if VI_DVALID is HIGH. If
VI_DVALID is LOW, VI_DATA is ignored. Clock and data rates of up to 81 MHz are
supported. PNX1300 Series supports an additional mode where VI_DATA[9:8] in
message passing mode are not affected by the VI_DVALID signal,
Section 6.6.1 on
page 6-12
.
If configured as output: programmable output clock to drive an external video A/D
converter. Can be programmed to emit integral dividers of DSPCPU_CLK.
If used as output, a board level 27-33 ohm series resistor is recommended to reduce
ringing.
VI_DVALID indicates that valid data is present on the VI_DATA lines. If HIGH, VI_DATA
will be accepted on the next VI_CLK positive edge. If LOW, no VI_DATA will be sam-
pled. PNX1300 Series supports an additional mode where VI_DATA[9:8] in message
passing mode are not affected by the VI_DVALID signal,

CCIR656 style YUV 4:2:2 data from a digital camera, or general purpose high speed
data input pins. Sampled on VI_CLK if VI_DVALID HIGH.

Extension high speed data input bits to allow use of 10 bit video A/D converters in
raw10 modes. VI_DATA[8] serves as START and VI_DATA[9] as END message input in
message passing mode. Sampled on positive transitions of VI_CLK if VI_DVALID
HIGH. PNX1300 Series supports an additional mode where VI_DATA[9:8] in message
passing mode are not affected by the VI_DVALID signal,
