Mode Control Register
Indirect (Write Only) Register Index 0x00
This register holds configuration data for the ADV601LC’s video interface format and controls several other video interface features.
For more information on formats and modes, see the Video Interface section. Bits in this register have the following functions:
[3:0]
[4]
FIFO Error, FIFOERR. This condition indicates that the host has been unable to keep up with the ADV601LC’s compressed
data supply or demand requirements. If this condition occurs during encode, the data stream will not be corrupted until
MERR indicates that the DRAM is also overflowed. If this condition occurs during decode, the video output will be
corrupted. If the system overflows the FIFO (disregarding a FIFOSTP condition) with too many writes in decode mode,
FIFOERR is asserted. This read only status bit indicates the following:
0
1
FIFO Stop, FIFOSTP. This condition indicates that the FIFO is full in decode mode and empty in encode mode.
In decode mode only, FIFOSTP status actually behaves more conservatively than this. In decode mode, even when
FIFOSTP is indicated, there are still 32 empty Dwords available in the FIFO and 32 more Dword writes can safely
be performed. This status bit indicates the following:
0
1
Memory Error, MERR. This condition indicates that an error has occurred at the DRAM memory interface. This condition can
be caused by a defective DRAM, the inability of the Host to keep up with the ADV601LC compressed data stream, or bit errors
in the data stream. Note that the ADV601LC recovers from this condition without host intervention.

Video Interface Format, VIF[3:0]. These bits select the interface format. Valid settings include the following (all
other values are reserved):

FIFO overflow (encode) or underflow (decode) (FIFO_ERR pin HI)
No FIFO Stop condition, reset value (FIFO_STP pin LO)
FIFO empty (encode) or full (decode) (FIFO_STP pin HI)
No memory error condition, reset value
Memory error
Disable CCIR-656 data error interrupt, reset value
Enable interrupt on error in CCIR-656 data
