DREQ1
1
O
Data Request for External DMA Interface.
Indicates that the ADV212 is ready to
send/receive data to/from the FIFO assigned
to DMA Channel 1.
FSRQ1
O
FIFO Service Request. Used in DCS-DMA
mode. Service request from the FIFO assigned
to Channel 1 (asynchronous mode).
CFG2
I
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 DGND through a 10 k resistor.

DACK1
1
I
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.
FCS1
I
FIFO Chip Select. Used in DCS-DMA mode.
Chip select for the FIFO assigned to Channel 1
(asynchronous mode).

SCOMM5
I/O
Serial Communication. This pin must be used
in multiple chip mode to align the outputs of
two or more ADV212s. For details, see the
used, this pin should be tied low via a 10 k
resistor.

O
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.
