Description
Reserved
This bit is always read as 0. The write value should
always be 0.
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 area. The
read and write cycles which are performed consecutively
and are accessed to different areas are the target cycle.
000: No idle cycle inserted
001: 1 idle cycles inserted
010: 2 idle cycles inserted
011: 4 idle cycles inserted
Reserved
This bit is always read as 0. The write value should
always be 0.
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 area. The
read and write cycles which are performed consecutively
and are accessed to the same area are the target cycle.
000: No idle cycle inserted
001: 1 idle cycles inserted
010: 2 idle cycles inserted
011: 4 idle cycles inserted
Reserved
This bit is always read as 0. The write value should
