switch hold position

[john.stm]

i have a motor which
rotates in clockwise if switch s1 is actuated or
rotates in Anti-clockwise if switch s2 is actuated. (both are separate switches)

In my logic it is stated that s1 state must be saved . (can i use a flip flop or latch or shift register ? )

It is also stated that S1-hold state .. what exactly it means and how can i realize it?

dont use a latch. Use a flip flop (a shift register is just a chain of flip flops).

To hold a state, have an enable signal that only moves the state machine on when the enable is high.
