VXI SM8000 user manual Control Register Write Only, Offset Register Read and Write

VXI Technology, Inc.

	Control Register – Write Only
ADDR	Plug-In LA+0x04
D15	A24/A32 Enable	1	= write a 1 to this bit to enable A24/A32 memory access
		0	= to disable access
D14-D2	Reserved	Writes to these bits have no effect.
D1	Sysfail Inhibit	Write a 1 to this bit to prevent the module from asserting the
		SYSFAIL* line.
D0	Reset	1	= write a 1 to this bit to force the module into a reset state
		0	= write a 0 to release the reset state

	Offset Register – Read and Write
ADDR	Plug-In LA+0x06
		The value written to this 16-bit register, times 256, sets the base
		address of the A24 memory space used by the module. The value
		written to this 16-bit register, times 65,536, sets the base address
D15-D0	A24/A32 Memory	of the A32 memory space used by the module. A read from this
		register reflects the previously written value. Because of the
	Offset
		required memory size, bits D4-D0 are disregarded on writes and
		always read back as 0s. Upon receiving a hard reset, all bits in
		this register are set to 0s. A soft reset does not effect the value in
		this register. The resource manager sets this register.
