DSCLK and DSI are internally synchronized. This setup time must be met only if recognition
on a particular clock is required.
AC timing specs assume 50pF load capacitance on PSTCLK and output pins. If this value is
different, the input and output timing specifications would need to be adjusted to match the
clock load.
