BBRAM/TOD Clock Memory Map

The MK48T08 BBRAM (also called Non-Volatile RAM or NVRAM)
is divided into six areas as shown in Table 1-11. The first five areas
are defined by software, while the sixth area, the time-of-day (TOD)
clock, is defined by the chip hardware. The first area is reserved for
user data. The second area is used by Motorola networking
software. The third area may be used by an operating system. The
fourth area is used by the MVME162FX board debugger
(MVME162Bug). The fifth area, detailed in Table 1-12, is the
configuration area. The sixth area, the TOD clock, detailed in Table
1-13, is defined by the chip hardware.
