Description
Turns the slave interface on or off. The default is off. When turned
off, other VME masters cannot access memory on the XVME-654.
Determines which type of VMEbus slave accesses are permitted to
read or write to the XVME-654 dual-access DRAM. The first field
determines whether the slave interface responds to Data accesses
only, or to both Program and Data Accesses. The default is Data.
The second field determines whether the slave interface responds
to Supervisory accesses only, or to both Supervisory and Non-
Privileged accesses. The default is Non-Privileged.
Determines if VME masters access the slave's dual-access memory
in the VMEbus Standard (A24) or VMEbus Extended (A32) address
space. The default is VMEbus extended.
Determines the amount of dual-access memory that is available to
external VMEbus masters when the Slave Address Space option is
set to Extended. If the Slave Address Space option is set to
Standard, the slave memory size is fixed at 4 Mbytes. The slave
memory size cannot be more than the total memory size. The
default is 4 Mbytes.
Sets the VMEbus address of the XVME-654 dual-access RAM.
When the Slave Address Space option is set to VMEbus Standard
(A24), the dual-access memory must be located on a 4-Mbyte
boundary and the upper two hex digits of the slave address are
ignored. When the Slave Address Space option is set to VMEbus
Extended (A32), the slave address must be a multiple of the slave
memory size. The default is AA4.
