All DSPI timing specifications use the fastest slew rate (SRC = 0b11) on medium-speed pads. DSPI signals using
slow pads have an additional delay based on the slew rate. DSPI timing is specified at V
V
Data is verified at f
The minimum DSPI Cycle Time restricts the baud rate selection for given system clock rate. These numbers are
calculated based on two MPC5644A devices communicating over a DSPI link.
