The VIMS module forwards CPU accesses (icode/dcode) and system bus accesses to the addressed
memories; the VIMS module also arbitrates access between the CPU and the system bus.
The VIMS module runs on the 48-MHz system clock.
The flash memory is programmable from user software, from the debug interface, and from the ROM
bootloader. The RAM block can be used as a cache for the Flash block or as general purpose RAM.
