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.
