6.5.4 FlexCAN electical specifications

For supported baud rate, see section 'Protocol timing' of the Reference Manual.

6.5.5 SAI electrical specifications

The following table describes the SAI electrical characteristics.

• Measurements are with maximum output load of 50 pF, input transition of 1 ns and

pad configured with fastest slew settings (DSE = 1'b1).

• I/O operating voltage ranges from 2.97 V to 3.6 V

• While doing the mode transition (RUN -> HSRUN or HSRUN -> RUN ), the

interface should be OFF.
