Descriptions
External Bus Mode Enable
Sets the external bus mode. In modes 1, 2, and 4,
this bit is fixed at 1 and cannot be modified. In modes
3 and 7, this bit can be read from and written to.
Writing 0 to this bit when its value is 1 should only be
carried out when an external bus cycle is not being
executed.
0: External address space is disabled
1: External address space is enabled
RAM Enable
Enables or disables the on-chip RAM. This bit is
initialized when the reset state is canceled.
0: On-chip RAM is disabled
1: On-chip RAM is enabled
