Loopback Mode Input Group Definition and Input-to-Output Pin Mapping
Inputs are divided into 2 groups because there are up to 28 inputs to train (22 address, 2 control, and 4 KD clocks), but as few as 18
outputs available to loop them back to (in x18 devices).
There are 18 inputs per group - one per Q output in x18 devices, and one per two Q outputs in x36 devices.

Notes:
1. Blue shading indicates input pins that are unused (NU) in certain device configurations. During Loopback Mode, the associated
output pins loop back the states of those input pins regardless whether they are used or unused.
2. Gray shading indicates Group 2 inputs that are reserved (RSVD) for future use. During Loopback Mode, the associated output
pins act as if they were looping back input pins tied Low.
3. The 18 unused Q in x18 devices remain in their “NU” states during Loopback Mode.
