DSPI timing specified at VDDE_x = 3.0 V to 3.6 V, T
Parameter values guaranteed by design.
The minimum SCK Cycle Time restricts the baud rate selection for given system clock rate.
The actual minimum SCK Cycle Time is limited by pad performance.
Maximum clock possible is System clock/2.
The maximum value is programmable in DSPI_CTARx[PSSCK] and DSPI_CTARx[CSSCK], program PSSCK=2 & CSSCK = 2
The maximum value is programmable in DSPI_CTARx[PASC] and DSPI_CTARx[ASC]
This delay value is corresponding to SMPL_PT=00b which is bit field 9 and 8 of DSPI_MCR register.
