MVME162-022 board

MVME162-022

Sixteen bytes are reserved for the printed wiring assembly (PWA) number

assigned to this board in ASCII format. This includes the 01-W prefix. This

is for the main logic board if more than one board is required for a set.

Additional boards in a set are defined by a structure for that set. For

example, for an MVME162 board with MC68040, SCSI, Ethernet, 4MB

DRAM, and 512KB SRAM, at revision A, the PWA field contains:

01-W3814B01A (The 12 characters are followed by four blanks.)

Four bytes contain the speed of the board in MHz. The first two bytes are

the whole number of MHz and the second two bytes are fractions of MHz.

For example, for a 25.00 MHz board, this field contains

Description

MVME162-022
The MK48T08 BBRAM (also called Non-Volatile RAM or NVRAM) is divided
into six areas as shown in Table 3-10. 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 MVME162 board debugger
(MVME162Bug). The fifth area, detailed in Table 3-11, is the configuration
area. The sixth area, the TOD clock, detailed in Table is defined by the
chip hardware.
The data structure of the configuration bytes starts at $FFFC1EF8 and is as
follows.
