sp40/sp41

Note: There are four possible TDM timing conditions:

1. Input sampled on the rising edge and output driven on the rising edge (shown).

2. Input sampled on the rising edge and output driven on the falling edge.

3. Input sampled on the falling edge and output driven on the falling edge.

4. Input sampled on the falling edge and output driven on the rising edge.
