		Busy Trigger Control Register (0x3C) — Read and Write
			Sets the TTLTRIG Line or Lines, which are configured as outputs, and
			will toggle at the de-assertion of a Board Busy condition sent by the
	D15-D8	TTLTRIG Select	plug-in modules. D15 corresponds to TTLTRIG7, D14 to TTLTRIG6,
	D15-D8	TTLTRIG Select	… and D8 to TTLTRIG0. Setting a bit to a 1 enables the trigger line,

			setting a bit to a 0 disables the corresponding line. All bits are set to 0
			when either a soft or a hard reset is received by the module.
	D7-D1	Unused	Data written to these bits have no effect. The value written is read
	D7-D1	Unused	back.
			back.
			Enables the Board Busy signal received from the switch module to
	D0	Busy Trigger Enable	generate a trigger condition on the TTL Trigger Bus. Setting a bit to 1
	D0	Busy Trigger Enable	enables the generation of a Trigger condition, setting a bit to a 0
			disables the corresponding line. This bit is set to 0 when either a soft
			or a hard reset is received by the module.

Trigger Advance Register (0x3E) — Write Only

			Indicates whether the SMIP II platform is a single or double wide.
D6			0	= single wide
			1	= double wide
D5-D1	Unused		Data written to these bits have no effect.
			A 0 read from this bit indicates the relays on the switch module have
D0			settled, a 1 indicates that the relays on the switch module are still
			changing state.
