Description
Idle Cycles for Read-Read in Another Space
Specify the number of idle cycles to be inserted after
the access to a memory that is connected to the
space. The target cycle is a read-read cycle of which
continuous access cycles switch between different
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
Idle Cycles for Read-Read in the Same Space
Specify the number of idle cycles to be inserted after
the access to a memory that is connected to the
space. The target cycle is a read-read cycle of which
continuous access cycles 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
Reserved
This bit is always read as 0. The write value should
always be 0.
