Refer to the MPU Port and MPU Channel Attention registers in the MVME162 Embedded Controller Programmer’s Reference Guide. 2. After resetting, you must write the System Configuration Pointer to the command registers before writing to the MPU Channel Attention register. Writes to the System Configuration Pointer must be upper word first, lower word second. 

BBRAM, TOD Clock Memory Map 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 3-12, is defined by the chip hardware. The data structure of the configuration bytes starts at $FFFC1EF8 and is as follows.

The fields are defined as follows: 1. Four bytes are reserved for the revision or version of this structure. This revision is stored in ASCII format, with the first two bytes being the major version numbers and the last two bytes being the minor version numbers. For example, if the version of this structure is 1.0, this field contains: 0100 2. Twelve bytes are reserved for the serial number of the board in ASCII format. For example, this field could contain: 000000470476 3. Sixteen bytes are reserved for the board ID in ASCII format. For example, for an MVME162 board with MC68040, SCSI, Ethernet, 4MB DRAM, and 512KB SRAM, this field contains: MVME162-23 (The 10 characters are followed by six blanks.) 4. 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.)

 5. 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: 2500 6. Six bytes are reserved for the Ethernet address. The address is stored in hexadecimal format. (Refer to the detailed description in Chapter 4.) If the board does not support Ethernet, this field is filled with zeros. 7. These two bytes are reserved. 8. Two bytes are reserved for the local SCSI ID. The SCSI ID is stored in ASCII format. 9. Eight bytes are reserved for the printed wiring board (PWB) number assigned to the memory mezzanine board in ASCII format. This does not include the 01-W prefix. For example, for a 4MB parity mezzanine at revision A, the PWB field contains: 3837B02A 10. Eight bytes are reserved for the serial number assigned to the memory mezzanine board in ASCII format.
