Description
1
R/W
Idle Cycles for Read-Read in Another Space
1
R/W
Specify the number of idle cycles to be inserted after
the access to a memory that is connected to the
1
R/W
space. The target cycle is a read-read cycle of which
continuous accesses switch between different spaces.
000: No idle cycle inserted
001: 1 idle cycle 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
1
R/W
Idle Cycles for Read-Read in the Same Space
1
R/W
Specify the number of idle cycles to be inserted after
the access to a memory that is connected to the
1
R/W
space. The target cycle is a read-read cycle of which
continuous accesses are for the same space.
000: No idle cycle inserted
001: 1 idle cycle 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

This bit is always read as 0. The write value should
always be 0.
