IWRWD0 1
R/W 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 cycle inserted
010: 2 idle cycles inserted
011: 4 idle cycles inserted
