Description
External Hold Indication for JDATA Input/Output Stream.
Polarity is programmable in the EDMOD0 register. This pin
is always an input.
Used in DCS-DMA Mode. Chip select for the FIFO assigned
to Channel 0 (asynchronous mode).
Data Request for External DMA Interface. Indicates that
the ADV202 is ready to send/receive data to/from the FIFO
assigned to DMA Channel 1.
Used in DCS-DMA Mode. Service request from the FIFO
assigned to Channel 1 (asynchronous mode).
Boot Mode Configuration. This pin is read on reset to
determine the boot configuration of the on-board
processor. The pin should be tied to IOVDD or DGND
through a 10 kΩ resistor.
Data Acknowledge for External DMA Interface. Signal
from the host CPU, which indicates that the data transfer
request (DREQ1) has been acknowledged and data
transfer can proceed. This pin must be held high at all
times unless a DMA or JDATA access is occurring. This pin
must be held high at all times if the DMA interface is not
used, even if the DMA channels are disabled.
Used in DCS-DMA Mode. Chip select for the FIFO assigned
to Channel 1 (asynchronous mode).
Host Expansion Bus.
JDATA Bus (JDATA Mode).
Host Expansion Bus.
JDATA Bus (JDATA Mode).
Host Expansion Bus.
When not used, this pin should be tied low via a 10 kΩ
resistor.
When not used, this pin should be tied low via a 10 kΩ
resistor.
This pin must be used in multiple chip mode to align the
outputs of two or more ADV202s. For details, see the
Applications section and AN-796
Application
should be tied low via a 10 kΩ resistor.
LCODE Output in Encode Mode. When LCODE is enabled,
the output on this pin indicates on a high transition that
the last data-word for a field has been read from the FIFO.
For an 8-bit interface, such as JDATA, LCODE is asserted for
four consecutive bytes and is enabled by default.
This pin should be tied low via a 10 kΩ resistor.
This pin should be tied low via a 10 kΩ resistor.
This pin should be tied low via a 10 kΩ resistor.
This pin should be tied low via a 10 kΩ resistor.
Video Data Clock. Must be supplied if video data is
input/output on the VDATA bus.
Video Data. Unused pins should be pulled down via a
10 kΩ resistor.
Vertical Sync for Video Mode.
Raw Pixel Mode Framing Signal. Indicates first sample of a
tile when asserted high.
Horizontal Sync for Video Mode.
Raw Pixel Mode Ready Signal.
