Operating conditions: CL = 10 to 50 pF, SlewIN = 3.5 to 15 ns.

Maximum value is reached when CSn pad is configured as SLOW pad while SCK pad is configured as MEDIUM. A positive value means that SCK starts before CSn is

asserted. DSPI2 has only SLOW SCK available.

Maximum value is reached when CSn pad is configured as MEDIUM pad while SCK pad is configured as SLOW. A positive value means that CSn is deasserted before

SCK. DSPI0 and DSPI1 have only MEDIUM SCK available.

The tCSC delay value is configurable through a register. When configuring tCSC (using PCSSCK and CSSCK fields in DSPI_CTARx registers), delay between internal CS

and internal SCK must be higher than

t

CSC to ensure positive tCSCext.

The tASC delay value is configurable through a register. When configuring tASC (using PASC and ASC fields in DSPI_CTARx registers), delay between internal CS and

internal SCK must be higher than

t

ASC to ensure positive tASCext.

This delay value corresponds to SMPL_PT = 00b which is bit field 9 and 8 of the DSPI_MCR.
