1. Operating in pass-through mode: regulator output voltage equal to the input voltage minus a drop proportional to I
6.8.4 DSPI switching specifications (low-speed mode)
The DMA Serial Peripheral Interface (DSPI) provides a synchronous serial bus with
master and slave operations. Many of the transfer attributes are programmable. The tables
below provides DSPI timing characteristics for classic SPI timing modes. Refer to the
DSPI chapter of the Reference Manual for information on the modified transfer formats
used for communicating with slower peripheral devices.
