Interrupt Control Register (0x1C) — Read and Write

	D15	Scan Function done	0	= enabled
		mask bit	1	= disabled

	D14	Openbus Active Event	0	= enabled
		true mask bit	1	= disabled

	D13-D9	Unused	Data written to these bits has no effect
	D8	Module Busy Complete	0	= enabled
			1	= disabled

	D7	IR ENA*	0	= writing a 0 to this bit enables interrupter capabilities
			1	= writing a 1 to this bit disables interrupter capabilities

	D6	IH ENA*	The module has no interrupt handler capability; therefore writing a 1 or
			0 has no effect. A 1 is always read back for this bit.

			The complement of the value programmed into these three bits reflects
	D5-D3	Interrupter IRQ Line	the selected IRQ line used by the module. A value of 0112 would select
			IRQ4, a value of 0002 would select IRQ7, and a value of 1112 would

			disconnect the IRQ lines.
	D2-D0	Handler IRQ Line	The module has no interrupt handler capability; therefore writing to
			these bits has no effect. A 1112 is always read back for these bits.

	Note that all bits in this register are set to 1 upon receipt of a hard or soft reset.

		Subclass Register (0x1E) — Read Only
	D15	VXIbus Extended	Always reads as 1.
		Device

	D14-D0	Extended Memory	Always reads as 7FFD16
		Device

			NVM Access Resister (0x20) — Read Only
	D15-D1	Unused		All Bits are always 1.
	D0			Reads back the serial data stream from the selected SMIP II board.
	D0			Note that only one SMIP II board may be read back at a time.

			NVM Access Resister (0x20) — Write Only
	D15-D2	Unused		Data written to these bits have no effect.
	D1			Serial clock for the switch module; should be a logic 1 when not used.
	D0			Serial data input for the switch module; must be a logic 1 when not
	D0			used.
				used.

Board X, Y Used Address Register (0x22, 0x24, 0x26) — Read and Write

D15-D8		Sets the actual number of words of address space used by the relays on
D15-D8		board's X.
		board's X.
D7-D0		Sets the actual number of words of address space used by the relays on
D7-D0		board's Y.
		board's Y.
