1. Remapped SPI1 characteristics to be determined.
2. Based on characterization, not tested in production.
3. Min time is for the minimum time to drive the output and the max time is for the maximum time to validate
4. Min time is for the minimum time to invalidate the output and the max time is for the maximum time to put
