Description
Read as 01h to indicate 32-bit I/O addressing
Defines the top address of the I/O address range for the bridge to
determine when to forward I/O transactions from one interface to
the other. The upper 4 bits correspond to address bits [15:12] and
are writable. The lower 12 bits corresponding to address bits [11:0]
are assumed to be FFFh. The upper 16 bits corresponding to
address bits [31:16] are defined in the I/O base address upper 16 bits

Reset to 1
Reset to 0
Set to 1 to enable decoding of fast back-to-back transactions on the
secondary interface to different targets
Reset to 0
Set to 1 when S_PERR_L is asserted and bit 6 of command register
is set

Reset to 01
Set to 1 (by a target device) whenever a target abort cycle occurs on
its secondary interface
Reset to 0
Set to 1 (by a master device) whenever transactions on its secondary
interface are terminated with target abort
Reset to 0
Set to 1 (by a master) when transactions on its secondary interface
are terminated with Master Abort
Reset to 0
Set to 1 when S_SERR_L is asserted
Reset to 0
Set to 1 when address or data parity error is detected on the
secondary interface
