DESCRIPTION
Asserted when correctable error is detected. Errors are logged in this
register regardless of whether error reporting is enabled or not in the
Device Control register.
Reset to 0b.
Asserted when non-fatal error is detected. Errors are logged in this
register regardless of whether error reporting is enabled or not in the
Device Control register.
Reset to 0b.
Asserted when fatal error is detected. Errors are logged in this
register regardless of whether error reporting is enabled or not in the
Device Control register.
Reset to 0b.
Asserted when unsupported request is detected. Errors are logged in
this register regardless of whether error reporting is enabled or not in
the Device Control register.
Reset to 0b.
Asserted when the AUX power is detected by the I/O bridge
Reset to 1b.
It is not implemented. Hardwired to 0b.
DESCRIPTION
Reset to 000h.
DESCRIPTION
0b: Disable Unsupported Request Reporting.
1b: Enable Unsupported Request Reporting.
Reset to 0b.
It is not implemented.
Reset to 0b.
This field sets maximum TLP payload size for the device.
Permissible values that can be programmed are indicated by the
Max_Payload_Size Supported in the Device Capabilities register.
Any value exceeding the Max_Payload_Size Supported written to
this register results into clamping to the Max_Payload_Size
Supported value.
Reset to 000b.
It is not implemented. Hardwired to 0b.
It is not implemented. Hardwired to 0b.
When set, indicates that the I/O bridge is enabled to draw AUX
power independent of PME AUX power.
Reset to 0b.
It is not implemented. Hardwired to 0b.
It is not implemented. Hardwired to 000b.
Reset to 0b.
