Type JK
No change if J=0 and K=0.
33K
Q goes 1 if J=1 and K=0 on 1-to-0 edge of C.
Q goes 0 if J=0 and K=1 on 1-to-0 edge of C.
Toggle Q if J=1 and K=1 on 1-to-0 edge of C.
Types S and R
Q goes 1 if S=1 on 1-to-0 edge of SC.
33K
Q goes 0 if R=1 on 1-to-0 edge of RC.
Types nS and nR
Q goes 1 if nS=0 on 1-to-0 edge of SC.
33K
Q goes 0 if nR=0 on 1-to-0 edge of RC.
Type D
Q follows D on 1-to-0 edge of C.
Type T
nQ
Toggle Q on 1-to-0 edge of T.
Type TETC
Toggle Q if nTE=0 on 1-to-0 edge of TC.
