This register defines the various control functions associated with the PCI bus. The register bits are defined
below.
Bit [31]
: Det. Par Err (R/W1C) – Detected Parity Error. This bit set indicates that the
SiI
3114 detected a
parity error on the PCI bus-address or data parity error-while responding as a PCI target.
Bit [30]
: Sig. Sys Err (R/W1C) – Signaled System Error. This bit set indicates that the
SiI
3114 signaled
SERR on the PCI bus.
Bit [29]
: Rcvd M Abort (R/W1C) – Received Master Abort. This bit set indicates that the
SiI
3114 terminated
a PCI bus operation with a Master Abort.
Bit [28]
: Rcvd T Abort (R/W1C) – Received Target Abort. This bit set indicates that the
SiI
3114 received a
Target Abort termination.
Bit [27]
: Sig. T Abort (R/W1C) – Signaled Target Abort. This bit set indicates that the
SiI
3114 terminated a
PCI bus operation with a Target Abort.
Bit [26:25]
: Devsel Timing (R) – Device Select Timing. This bit field indicates the DEVSEL timing supported
by the
SiI
3114. The hardwired value is 01
B
for Medium decode timing.
Bit [24]
: Det M Data Par Err (R/W1C) – Detected Master Data Parity Error. This bit set indicates that the
SiI
3114, as bus master, detected a parity error on the PCI bus. The parity error may be either reported by
the target device via PERR# on a write operation or by the
SiI
3114 on a read operation.
Bit [23]
: Fast B-to-B Capable (R) – Fast Back-to-Back Capable. This bit is hardwired to 1 to indicate that
the
SiI
3114 is Fast Back-to-Back capable as a PCI target.
Bit [22]
: Reserved (R).
Bit [21]
: 66 MHz Capable (R) – 66 MHz PCI Operation Capable. This bit is hardwired to 1 to indicate that
the
SiI
3114 is 66 MHz capable.
Bit [20]
: Capabilities List (R) – PCI Capabilities List. This bit is hardwired to 1 to indicate that the
SiI
3114
has a PCI Power Management Capabilities register linked at offset 34
H
.
Bit [19]
: Interrupt Status (R)
Bit [18:11]
: Reserved (R). This bit field is reserved and returns zeros on a read.
Bit [10]
: Interrupt Disable (R/W).
Bit [09]
: Fast B-to-B Enable (R) – Fast Back-to-Back Enable. This bit is hardwired to 0 to indicate that the
SiI
3114 does not support Fast Back-to-Back operations as bus master.
Bit [08]
: SERR Enable (R/W) – SERR Output Enable. This bit set enables the
SiI
3114 to drive the PCI
SERR# pin when it detects an address parity error. The Parity Error Response bit (06) must also be set to
enable SERR# reporting.
Bit [07]
: Address Stepping (R) – Address Stepping Enable. This bit is hardwired to 0 to indicate that the
SiI
3114 does not support Address Stepping.
Bit [06]
: Par Error Response (R/W) – Parity Error Response Enable. This bit set enables the
SiI
3114 to
respond to parity errors on the PCI bus. If this bit is cleared, the
SiI
3114 will ignore PCI parity errors.
Bit [05]
: VGA Palette (R) – VGA Palette Snoop Enable. This bit is hardwired to 0 to indicate that the
SiI
3114 does not support VGA Palette Snooping.
Bit [04]
: Mem Wr & Inv (R) – Memory Write and Invalidate Enable. This bit is hardwired to 0 to indicate that
the
SiI
3114 does not support Memory Write and Invalidate.
