(See note.)

Note: There are four possible timing conditions for SCC and SPI:

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.
