4.3.2.1 SRAM Base Address Register (RAMBAR)
RAMBAR determines the base address location of the internal SRAM module, as well as
the definition of the types of accesses allowed for it.
RAMBAR fields are described in Table 4-2.

CPU address space via the MOVEC instruction with an Rc encoding of 0xC04.
RAMBAR can be read or written in background debug mode (BDM). At system
reset, the V bit is cleared and the remaining bits are uninitialized. To access the
SRAM module, RAMBAR must be written with the appropriate base address after
system reset.
