Note: There are four possible timing conditions for SPI:
1. Input sampled on the rising edge and output driven on the rising edge.
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 (shown).
4. Input sampled on the falling edge and output driven on the rising edge.
Note: There are two possible timing conditions for SCC/SMC/I2C:
1. Input sampled on the falling edge and output driven on the falling edge (shown).
2. Input sampled on the falling edge and output driven on the rising edge.
