bits that the device allows to be writable is selected through the inbound window size in the inbound window
attributes registers (PEXIWAR2 for offset 0x1C and PEXIWAR3 for offset 0x24). If no access to local memory
is to be permitted by external requestors, then all bits are programmed.

of bits that the device allows to be writable is selected through the inbound window size in the inbound
window attributes registers (PEXIWAR2 for offset 0x18 and PEXIWAR3 for offset 0x20).
Reserved. The device allows a 4 Kbyte window minimum.
Prefetchable. This bit is determined by PEXIWAR n [2].
