Description
Idle Cycles for Another Space Read-Write
Specify the number of idle cycles to be inserted after the
access to a memory that is connected to the space. The
target access cycle is a read-write one in which continuous
accesses switch between different spaces.
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
Idle Cycles for Read-Write in 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-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
