SPI Characteristics
Table 23 and Figure 15 through Figure 18 describe the timing requirements for the SPI system.
Table 23. SPI Timing
No.1
1
Numbers in this column identify elements in Figure 15 through Figure 18.
Characteristic2
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.
