	Open Trigger Select Register – Write Only
ADDR	Plug-In LA+0x36
		Sets the TTLTRIG line or lines, which are configures as outputs,
		and will toggle when Relay Open condition occurs in the module.
D15-D8		D15 corresponds to TTLTRIG7, D14 to TTLTRIG6, … and D8 to
		TTLTRIG0. Setting a bit to a 1 enables the trigger line, setting a
		bit to 0 disables the corresponding line. All bits are set to 0s when
		either a soft or a hard reset is received by the module.
		Sets the TTLTRIG line or lines, which are configured as inputs,
		and will cause a Relay Open event to occur in the module. D7
		corresponds to TTLTRIG7, D6 to TTLTRIG6, … and D0 to
D7-D0		TTLTRIG0. Setting a bit to a 1 enables the trigger line, setting a
		bit to 0 disables the corresponding line. All enabled TTLTRIG
		lines are OR’d together to allow more than one TTLTRIG line to
		cause a Relay Open event to occur. All bits are set to 0s when the
		module receives either a soft or a hard reset.

D15-D14	Unused	Data written to these bits have no affect.
D13-D8	FAIL LED Control	D13 is for module 5 … D8 is for module 0. 0 = off, 1 = on.
D4	Board Busy	0 acts on the falling edge, 1 acts on the rising edge.
	Trigger Slope
D3	Relay Open Input	0 acts on the falling edge, 1 acts on the rising edge.
	Slope
D2	Relay Open Output	0 sets the falling edge active, 1 sets the rising edge active.
	Slope
D1	Trace Advance	0 advances on the falling edge, 1 advances on the rising edge.
	Input Slope
D0	Trace Advance	0 sets the falling edge active, 1 sets the rising edge active.
	Output Slope

Note: A hard or a soft reset sets D3-D0 to 0 s.
