SPI Characteristics
Table 3-14 and Figure 3-15 through Figure 3-18 describe the timing requirements for the SPI system.
Table 3-14. SPI Electrical Characteristic
Num1
1 Refer to Figure 3-15 through Figure 3-18.
C
Characteristic2
2 All timing is shown with respect to 20% V
DD 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.
