Figure 41-3. Masked Input Selection

Internal Feedback Inputs (FEEDBACK)

When selected (LUTCTRLx.INSELy=FEEDBACK), the Sequential (SEQ) output is used as input for the

corresponding LUT.

The output from an internal sequential sub-module can be used as input source for the LUT, see figure

below for an example for LUT0 and LUT1. The sequential selection for each LUT follows the formula:

IN 2N  = SEQ 

IN 2N+1  = SEQ 

With N representing the sequencer number and i=0,1,2 representing the LUT input index.

For details, refer to 41.6.2.7 Sequential Logic.

Linked LUT (LINK)

When selected (LUTCTRLx.INSELy=LINK), the subsequent LUT output is used as the LUT input (e.g.,

LUT2 is the input for LUT1), as shown in this figure:
