BBRAM, TOD Clock Memory Map
The MK48T08 BBRAM (also called Non-Volatile RAM or NVRAM) is
divided into six areas as shown in Table 1-14. 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 is
used by the operating system. The fourth area is used by the MVME162LX
board debugger (162Bug). The fifth area, detailed in Table 1-15, is the
configuration area. The sixth area, the TOD clock, detailed in Table 1-16,
is defined by the chip hardware.
The data structure of the configuration bytes starts at $FFFC1EF8 and is
as follows.
