ColdFire Core
3.2.3.5
The access control registers, ACR0 and ACR1, define attributes for two user-defined memory
regions. These attributes include the definition of cache mode, write protect, and buffer write
enables. The ACRs are described in
3.2.3.6
The RAMBAR register is used to specify the base address of the internal SRAM and indicate the
types of references mapped to it. The base address register includes a base address, write-protect
bit, address space mask bits, and an enable bit. For more information, refer to
