IWRWS0 1
R/W Specify the number of idle cycles to be inserted after the
R/W ^{access to a memory that is connected to the space. The}
target cycle is a read-write cycle of which continuous
accesses are for the same space.
000: No idle cycle inserted
001: 1 idle cycles inserted
010: 2 idle cycles inserted
011: 4 idle cycles inserted
100: 6 idle cycles inserted
101: 8 idle cycles inserted
110: 10 idle cycles inserted
111: 12 idle cycles inserted

R/W Specify the number of idle cycles to be inserted after the
R/W ^{access to a memory that is connected to the space. The}
target cycle is a read-read cycle of which continuous
accesses switch between different space.

011: 4 idle cycles inserted
100: 6 idle cycles inserted
101: 8 idle cycles inserted
110: 10 idle cycles inserted
111: 12 idle cycles inserted
