Description
Controls PI7C8150A’s detection mechanism for matching non-posted
memory write retry cycles from the initiator on the primary interface
0: exact matching for non-posted memory write retry cycles from
initiator on the secondary interface
1: alias MEMWI to MEMW for non-posted memory write retry
cycles from initiator on the secondary interface
Reset to 0
Reserved. Returns 0 when read. Reset to 0.
Controls PI7C8150A’s detection mechanism for matching non-posted
memory write and invalidate cycles from the initiator on the primary
interface
0: When accepting MEMWI command at the primary interface,
PI7C8150A converts MEMWI to MEMW command on the
secondary interface
1: Disconnects MEMWI command at aligned cache line boundaries
Controls PI7C8150A’s detection mechanism for matching non-posted
memory write and invalidate cycles from the initiator on the
secondary interface
0: When accepting MEMWI command at the secondary interface,
PI7C8150A converts MEMWI to MEMW command on the primary
interface
1: Disconnects MEMWI command at aligned cache line boundaries
Controls PI7C8150A’s ability to enable long requests for lock cycles
0: normal lock operation
1: enable long request for lock cycle
Reset to 0
Controls PI7C8150A’s ability to enable the secondary bus to hold
requests longer.
0: internal secondary master will release REQ_L after FRAME_L
assertion
1: internal secondary master will hold REQ_L until there is no
transactions pending in FIFO or until terminated by target
Reset to 1
Controls PI7C8150A’s ability to hold requests longer at the Primary
Port.
0: internal Primary master will release REQ_L after FRAME_L
assertion
1: internal Primary master will hold REQ_L until there is no
transactions pending in FIFO or until terminated by target
Reset to 1
Reserved. Returns 0 when read. Reset to 0.
