		20 kHz (Channels 0-3)/5 MHz (Channels 4-5) LPF Control – This bit
		enables/disables the low pass frequency filter for the low-speed channels
		and high-speed channels, respectively. . Before taking a measurement,
D4	FILTER	allow for at least 5 ms for internal circuits to settle after making changes.
		0 = Filter off
		1 = Filter on
		Pon state = 0
		Input Trigger Source Slope – This bit sets the slope of the input trigger
		for low-speed Channels 0 - 3.
D3	TRGSLOPE	0 = Positive
		1 = Negative
		Pon state = 0
		Trigger Source Control - Once the trigger is armed, the acquisition can
		be triggered via software (FTRIG), any of the six channels or an external
		trigger.
		000	= Channel 0
D2 – D0	TRIGSRC2 - 0	001	= Channel 1
		010	= Channel 2
		011	= Channel 3
		100	= Channel 4
		101	= Channel 5
		110	= External
		111	= External High-Speed

D15 – D12	Unused	This is reserved for future use.
		Trigger Level Threshold Setting – These bits set the trigger threshold
		(12-bit value).
D11 – D0	TRGLVL	0x800	= 0 V
		0x000	= -ve full scale
		0xFFF	= +ve full scale

Sample Rate (0x0C, 0x34, 0x5C, 0x84) — Read & Write

D15 – D9	Unused	These bits are reserved for future use.
		Sample Interval – These bits set the sample rate.
D8 – D0	SAMPRAT24 – 16	Bit Weight = 100 ns/bit
