PRI-64 MEMORY MAP ASSIGNMENT
Each PRI-64 board consumes a 512 byte window of VME-
bus space. Each PRI-64 board consumes a 2 Meg window of
VMEbus A32 space. The A32 base address of the board is con-
figured under software control during the boot procedure for
the board. Specifically, the 11 MSBs of the A32 base address
may be programmed.
The 7 MSBs of the PRI-64 A16 base address are specified
by the two rotary dials located on the front panel. The upper
dial specifies address bits A15-A12. The lower dial specifies
address bits A11-A09. Note that the LSB of the lower dial is
not used.
