LUT-Register Mode
LUT-Register mode allows third register capability in an ALM. Two internal feedback
loops allow combinational ALUT1 to implement the master latch and combinational
ALUT0 to implement the slave latch needed for the third register. The LUT register
shares its clock, clock enable, and asynchronous clear sources with the top dedicated
register.
