1. Item numbers refer to dimensions in Figure 21-1 and Figure 21-2.
2. All timing is shown with respect to 30% V_DD and 70% V_DD, unless otherwise noted; assumes 100 pF load on all SPI pins.
3. f_BUS = the currently active bus frequency for the microcontroller.
4. Time to data active from high-impedance state
5. With 100 pF on all SPI pins
