Half 1, clock signal is 1:

1. Latch A value is protected.

2. Latch A value is passed to latch B.

3. Latch B value becomes input to the logic circuit.

Half 2, clock signal is 0:

1. Latch B value becomes protected.

2. Latch A becomes enabled for writing and accepts the output of the logical circuit.
