1 Refer to Figure A-14 through Figure A-17.
2 All timing is shown with respect to 20% VDD and 70% VDD, unless noted; 100 pF load on all SPI pins. All timing assumes slew
rate control disabled and high drive strength enabled for SPI output pins.
3 Electrical characteristics only apply to the temperature rated devices marked with x.
4 Time to data active from high-impedance state.
5 Hold time to high-impedance state.
6 Maximum baud rate must be limited to 5 MHz due to input filter characteristics.
