Description
Controls PI7C7300A’s detection mechanism for matching memory
read retry cycles from the initiator on the primary interface
0: exact matching for non-posted memory write retry cycles from
initiator on the primary interface
1: alias MEMRL or MEMRM to MEMR for memory read retry
cycles from the initiator on the primary interface
Reset to 0
Controls PI7C7300A’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 primary interface
1: alias MEMWI to MEMW for non-posted memory write retry
cycles from initiator on the primary interface
Reset to 0
Controls PI7C7300A’s detection mechanism for matching memory
read retry cycles from the initiator on S1
0: exact matching for memory read retry cycles from initiator on the
S1 or S2 interface
1: alias MEMRL or MEMRM to MEMR for memory read retry
cycles from initiator on the S1 or S2 interface
Reset to 0
Controls PI7C7300A’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 S1 or S2 interface
1: alias MEMWI to MEMW for non-posted memory write retry
cycles from initiator on the S1 or S2 interface
Reset to 0
Reserved. Returns 0 when read. Reset to 0.
Controls PI7C7300A’s ability to enable long requests for lock cycles
0: normal lock operation
1: enable long request for lock cycle
Reset to 0
Control’s PI7C7300A’s ability to enable S1 or S2 to hold requests
longer.
0: internal S1 or S2 master will release REQ_L after FRAME_L
assertion
1: internal S1 or S2 master will hold REQ_L until there is no
transactions pending in FIFO or until terminated by target
Reset to 1
