When the EAE bit in BCRL is set to 1, this area is external address space.
When the EAE bit is cleared to 0, it is on-chip ROM.
When the EAE bit in BCRL is set to 1, this area is reserved.
When the EAE bit is cleared to 0, it is on-chip ROM.
External addresses can be accessed by clearing the RAME bit in SYSCR to 0.
