Num
DSPI timing specified at VDD = 1.35V to 1.65V, VDDEH = 3.0V to 5.5V, VDD33 and VDDSYN = 3.0V to 3.6V, T
and CL = 50pF with SRC = 0b11.
The minimum SCK Cycle Time restricts the baud rate selection for given system clock rate. These numbers are calculated
based on two MPC55xx devices communicating over a DSPI link.
The actual minimum SCK Cycle Time is limited by pad performance.
The maximum value is programmable in DSPI_CTARx[PSSCK] and DSPI_CTARx[CSSCK]
The maximum value is programmable in DSPI_CTARx[PASC] and DSPI_CTARx[ASC]
This number is calculated assuming the SMPL_PT bit field in DSPI_MCR is set to 0b10.
