Field Description
0
MSTR
Master or slave mode select. Configures the DSPI for master mode or slave mode.
0 DSPI is in slave mode
1 DSPI is in master mode
1
CONT_SCKE
Continuous SCK enable. Enables the serial communication clock (SCK) to run continuously.
See Section 20.4.8, “Continuous Serial Communications Clock,” for details.

DCONF
[0:1]
DSPI configuration. Selects between the three different configurations of the DSPI. The following table lists
the DCONF values for the various configurations.
4
FRZ
Freeze. Enables the DSPI transfers to be stopped on the next frame boundary when the device enters debug
mode.
0 Do not halt serial transfers
1 Halt serial transfers
