2.2.2.3
The CACR controls operation of the instruction and data cache memory. It includes bits for enabling,
freezing, and invalidating cache contents. It also includes bits for defining the default cache mode and
write-protect fields. See
2.2.2.4
The access control registers (ACR0–ACR1) define attributes for two user-defined memory regions.
Attributes include definition of cache mode, write protect, and buffer write enables. See
“Access Control Registers (ACR0 and
2.2.2.5
The ROMBAR base address register determines the base address of the internal ROM module and
indicates the types of references mapped to it. The ROMBAR includes a base address, write-protect bit,
address space mask bits, and an enable. Note that the MCF5272 ROM contains data for the HDLC module
and is not user programmable. See
2.2.2.6
The RAMBAR register determines the base address location of the internal SRAM module and indicates
the types of references mapped to it. The RAMBAR includes a base address, write-protect bit, address
space mask bits, and an enable. The RAM base address must be aligned on a 0-modulo-4-Kbyte boundary.
See
2.2.2.7
The module base address register (MBAR) defines the logical base address for the memory-mapped space
containing the control registers for the on-chip peripherals. See
