; R1 contains the virtual address of a region of memory to configure as data RAM,
; which is aligned on a 32-byte boundary.
; MMU is configured so that the memory region is cacheable.
; R0 is the number of 32-byte lines to designate as data RAM. In this example 16
; lines of the data cache are re-configured as data RAM.
