PCI base address for odd fields
of the upper (or lower if pitch is
negative) left pixel of the transferred field
PCI base address for even fields
of the upper (or lower if pitch is
negative) left pixel of the transferred field
protection address
reserved
distance between the start addresses of two consecutive lines of a single
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

reserved
endian swapping
of all Dwords passing the FIFO 1:
00 = no swap
01 = two bytes swap (3210 to 2301)
10 = four bytes swap (3210 to 0123)
11 = reserved
Number of lines per field;
it defines the number of qualified lines to be
processed by the HPS per field. This will cut off all the following input lines
at the HPS input.
Number of pixels per line
; it defines the number of qualified pixels to be
processed by the HPS per line. This will cut off all the following pixels at
the HPS input.
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
