DESCRIPTION OF REGISTERS - A16

The following describes the registers shown in the SMIP II Register Map for A16 address space.

			ID Register (0x00) — Read Only
	D11-D0	Manufacturer's ID		VXI Technology, Inc., set to F4B16
	D13-D12	Address Space		A16/A24 = 002
	D13-D12	Address Space		A16/A32 = 012
				A16/A32 = 012
	D15-D14	Device Class		Extended register based device, set to 012

		Logical Address Register (0x00) — Write Only
			Sets the new logical address in a dynamically configured module.
	D7-D0	Logical Address	When set for dynamic configuration (set to FF16) a soft reset will not
	D7-D0	Logical Address	alter the configured logical address, while a hard reset will set the

			register back to FF16.
	D15-D8	Reserved	Writing to this range has no effect.

Device Type Register (0x02) — Read Only

	D11-D0	Model Code	Model 277, set to 11516
	D15-D12	Required Memory	2	Mbytes, set to 216, for A24
			2	Mbytes, set to A16, for A32

Status Register (0x04) — Read Only

	D15	A24/A32 Active	1	= indicates that A24/A32 memory space access is enabled
			0	= indicates that A24/A32 memory space access is locked out

	D14	MODID*	1	= indicates that the module is not selected by the MODID line
			0	= indicates that the module is selected by the MODID line.

	D13-D4	Reserved	These bits always read as 11,1111,11112
	D3	Ready	This bit always reads as 12
	D2	Passed	This bit always reads as 12
	D1-D0	Reserved	These bits always read as 112

Control Register (0x04) — Write Only

	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
