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
Reset to 0
Description
Lower four bits of register are read only and return 0.
Reset to 0
Defines the bottom address of an address range for the bridge to
determine when to forward memory transactions from one interface
to the other. The upper 12 bits correspond to address bits [31:20]
and are writable. The lower 20 bits corresponding to address bits
[19:0] are assumed to be 0.

to the other. The upper 12 bits correspond to address bits [31:20]
and are writable. The lower 20 bits corresponding to address bits
[19:0] are assumed to be FFFFFh.
