2.1.3 Offset_04 Command Register
The register provides control over the device’s ability to generate and respond to PCI cycles.
Bits
R/W
Description
0
R
I/O enable
Constant value of 0. The
μ
PD72862 does not respond to PCI I/O accesses.
1
R/W
Memory enable
Default value of 1. It defines if the
μ
PD72862 responds to PCI memory
accesses. This bit should be set to one upon power-up reset.
0: The
μ
PD72862 does not respond to PCI memory cycles
1: The
μ
PD72862 responds to PCI memory cycles
2
R/W
Master enable
Default value of 1. It enables the
μ
PD72862 as bus-master on the PCI-bus.
0: The
μ
PD72862 cannot generate PCI accesses by being a bus-master
1: The
μ
PD72862 is capable of acting as a bus-master
3
R
Special cycle monitor enable
Constant value of 0. The special cycle monitor is always
disabled.
4
R/W
Memory write and invalidate enable
Default value of 0. It enables Memory Write and Invalid
Command generation.
0: Memory write must be used
1: The
μ
PD72862, when acts as PCI master, can generate the command
5
R
VGA color palette invalidate enable
Constant value of 0. VGA color palette invalidate is
always disabled.
6
R/W
Parity error response
Default value of 0. It defines if the
μ
PD72862 responds to PERR.
0: Ignore parity error
1: Respond to parity error
7
R
Stepping enable
Constant value of 0. Stepping is always disabled.
8
R/W
System error enable
Default value of 0. It defines if the
μ
PD72862 responds to SERR.
0: Disable system error checking
1: Enable system error checking
9
R
Fast back-to-back enable
Constant value of 0. Fast back-to-back transactions are only
allowed to the same agent.
15-10
