5.2.1.4 Direct Input Register

This register provides the current state of the input signals.

Direct Input Register
Channel Offset Read Only	7	6	5	4	3	2	1	0
$09	F_Ua2	F_Ua1	F_DI	F_IND	Ua2	Ua1	DI	IND

F_Ua2: This bit is set when a non-differential input signal is detected on the Ua2 input. This bit will stay set until the Direct Input Register is read.
F_Ua1: This bit is set when a non-differential input signal is detected on the Ua1 input. This bit will stay set until the Direct Input Register is read.
F_DI: This bit is set when a non-differential input signal is detected on the digital input. This bit will stay set until the Direct Input Register is read.
F_IND: This bit is set when a non-differential input signal is detected on the index input. This bit will stay set until the Direct Input Register is read.
Ua2, Ua1: These bits directly reflect the state of the channel's quadrature signals.
DI: This bit directly reflects the state of the channel's digital input signal.
IND: This bit directly reflects the state of the channel's index input signal.
