Function
15:10
R
RO
Reserved. These bits always return zero.
9
FBACK_ENB
RO
Fast Back-to-Back Enable: the SAA7780, function 0 does not support fast
back to back master cycles therefore this bit always returns a zero.
8
SERR_RESP
RW
System Error Response: When set to 1, the SAA7780, function 0 responds to
detected PCI bus address parity errors by asserting SERR#. When 0, the
SAA7780 ignores these errors.
7
STEPPING
RO
Address / Data Stepping: Always returns 0.
6
PERR_RESP
RW
Parity Error Response: When set to 1, the SAA7780, function 0 responds to
detected PCI bus data parity errors by asserting PERR#. When 0, the
SAA7780 ignores PCI bus data parity errors.
5
SNOOP_ENB
RO
VGA Snoop Enable. The SAA7780, function 0 does not support VGA snoop
enable, therefore this bit always returns a zero.
4
MEM_INV_EN
RO
Memory Write and Invalidate Enable: Always returns 0.
3
SPEC_CNTL
RO
Special Cycle Control: Controls the devices ability to respond to Special
Cycle Operations. A value of 0 causes the SAA7780, function 0 to ignore all
Special Cycles.
2
MAST_CNTL
RW
Master Control: Controls the devices ability to act as a master on the PCI bus.
A value of 0 disables the ability of the SAA7780, function 0, to act as a
primary PCI master. A value of 1 enables the SAA7780, function 0 to become
a PCI bus master.
1
MEM_CNTL
RO
Memory Response Control: The SAA7780, function 0 does not support target
memory cycles therefore this bit always returns a zero.
0
IO_CNTL
RW
I/O Response Control: Controls the SAA7780, function 0’s response to I/O
space. A value of 0 disables the device response. A value of 1 allows the
device to respond to I/O space accesses.
