Operating Instructions

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
3
3		example, for a 32 megabyte, 50 MHz MVME197LE board at revision A, the

PWA field contains:

01-W3869B03A

(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 50 MHz board, this field contains:

5000

6.Eight bytes are reserved for the Ethernet address. The address is stored in hexadecimal format, with the last two bytes not used. (Refer to the Ethernet Interface section for a more detailed description). If the board does not support Ethernet, this field is filled with zeros.

7.Growth space (195 bytes) is reserved. This pads the structure to an even 256 bytes. Board-specific items, such as mezzanine board PWA numbers, may go here.

8.The final one byte of the area is reserved for a checksum (as defined in the MVME197BUG 197Bug Debugging Package User’s Manual) for security and data integrity of the configuration area of the NVRAM. This data is stored in hexadecimal format.

VMEbus Memory Map

This section describes the mapping of local resources as viewed by VMEbus masters.

VMEbus Accesses to the Local Peripheral Bus

The VMEchip2 includes a user-programmable map decoder for the VMEbus to local peripheral bus interface. The map decoder allows the user to program the starting and ending address and the modifiers the MVME197 responds to.

VMEbus Short I/O Memory Map

The VMEchip2 includes a user-programmable map decoder for the GCSR (Global Control and Status Registers). The GCSR map decoder allows the user to program the starting address of the GCSR in the VMEbus short I/O space.
