Flash Memory Control Register Enable
Controls CPU access to the flash memory control
registers (FLMCR1, FLMCR2, EBR1, and EBR2). If
this bit is set to 1, the flash memory control registers
can be read from and written to. If this bit is cleared to
0, the flash memory control registers are not selected.
At this time, the contents of the flash memory control
registers are maintained. This bit should be written to
0 in other than flash memory version.
0: Flash memory control registers are not selected for
1: Flash memory control registers are selected for
Reserved
This bit is always read as 0 and cannot be modified.
External Bus Mode Enable
Sets 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 of 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 bus disabled
1: External bus enabled
RAM Enable
Enables or disables the on-chip RAM. The RAME bit
is initialized when the reset state is released.
0: On-chip RAM is disabled
1: On-chip RAM is enabled
