NOTES:
1. All timing is shown with respect to 30% VDD and 70% VDD, unless otherwise noted; assumes 100 pF load on all SPI
pins.
2. Item numbers refer to dimensions in Figure 24-1 and Figure 24-2.
3. fBUS = 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
