DSPI Timing Specifications
The DMA Serial Peripheral Interface (DSPI) provides a synchronous serial bus with both master and slave operations. Many
of the transfer attributes are programmable. Table 26 provides DSPI timing characteristics for classic SPI timing modes. Refer
to the DSPI chapter of the MCF5301x Reference Manual for information on the modified transfer formats used for
communicating with slower peripheral devices.
