All DSPI timing specifications use the fastest slew rate (SRC = 0b11) on pad type M or MH. DSPI signals using pad types of S or SH have
an additional delay based on the slew rate. DSPI timing is specified at V
The minimum SCK cycle time restricts the baud rate selection for the 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 using the SMPL_PT field in DSPI_MCR set to 0b10.
Speed is the nominal maximum frequency. Max speed is the maximum speed allowed including frequency modulation (FM).
82 MHz parts allow for 80 MHz system clock + 2% FM; 114 MHz parts allow for 112 MHz system clock + 2% FM; and
135 MHz parts allow for 132 MHz system clock + 2% FM; and 147 MHz parts allow for 144 MHz system clock + 2% FM.
