TYPE
Specifies the data stream direction of FIFO 2. A logic 0 enables a write
operation to the PCI memory. A logic 1 enables a read operation from the
PCI memory.
endian swapping of all Dwords passing the FIFO 2:
Number of lines per field: in read mode NumLines defines the number of
lines to be read from system memory. A logic 0 specifies one line. In write
mode this register is not used.
Number of bytes per line: in read mode this defines the number of bytes
per line to be read from system memory. A logic 0 specifies one byte. In
write mode this register is not used.
PCI base address for odd fields of the upper (or lower if top-down flip is
selected) left pixel of the transferred field
PCI base address for even fields of the upper (or lower if top-down flip is
selected) left pixel of the transferred field
protection address
reserved
distance between the start addresses of two consecutive lines of a field
base address of the page table (see Section 7.2.4)
mapping enable; this bit enables the MMU
reserved
interrupt limit; defines the size of the memory range, that raise an
interrupt, if its boundaries are passed
protection violation handling
Specifies the data stream direction of FIFO 3. A logic 0 enables a write
operation to the PCI memory. A logic 1 enables a read operation from the
PCI memory.
endian swapping of all Dwords passing the FIFO 3:
Number of lines per field: in read mode NumLines defines the number of
lines to be read from system memory. A logic 0 specifies one line. In write
mode it defines the number of qualified lines to be processed by the BRS
per field. This will cut off all the following input-lines at the BRS input.
Number of bytes per line: in read mode this defines the number of bytes
per line to be read from system memory. A logic 0 specifies one byte. In
write mode it defines the number of qualified bytes to be processed by the
BRS per line. This will cut off all the following bytes at the BRS input.
00 = no swap
01 = 2-byte swap (3210 to 2301)
10 = 4-byte swap (3210 to 0123)
11 = reserved
