Reset to 0b.
When set, it permits the device to set the Relaxed Ordering bit in the attribute
field of transaction. Since the Switch can not either act as a requester or alter
the content of packet it forwards, this bit always returns ‘0’ when read.
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.
Does not apply to PCI Express Switch. Returns ‘0’ when read.
Reset to 0.
Does not apply to PCI Express Switch. Returns ‘0’ when read.
Reset to 0b.
When set, indicates that a device is enabled to draw AUX power independent
of PME AUX power.
Reset to 0b.
When set, it permits to set the No Snoop bit in the attribute field of
transaction. Since the Switch can not either act as a requester or alter the
content of packet it forwards, this bit always returns ‘0’ when read.
Reset to 0b.
This field sets the maximum Read Request size for the device as a Requester.
Since the Switch does not generate read request by itself, these bits are
hardwired to 000b.
Reset to 000b.
Reset to 0b.
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.
