6.4 Communication interfaces
6.4.1 SPI switching specifications
The serial peripheral interface (SPI) provides a synchronous serial bus with master and
slave operations. Many of the transfer attributes are programmable. The following tables
provide timing characteristics for classic SPI timing modes. Refer to the SPI chapter of
the chip's reference manual for information about the modified transfer formats used for
communicating with slower peripheral devices. All timing is shown with respect to 20%
V
DD
 and 70% V
DD
, unless noted, and 100 pF load on all SPI pins. All timing assumes
slew rate control is disabled and high drive strength is enabled for SPI output pins.
