Clock Generation
Transfer Delays
SPCK
The SPI Baud rate clock is generated by dividing the CLK_SPI by a value between 1 and 255.
This allows a maximum operating baud rate at up to CLK_SPI and a minimum operating baud
rate of CLK_SPI divided by 255.
Programming the SCBR field at 0 is forbidden. Triggering a transfer while SCBR is at 0 can lead
to unpredictable results.
At reset, SCBR is 0 and the user has to program it at a valid value before performing the first
transfer.
The divisor can be defined independently for each chip select, as it has to be programmed in the
SCBR field of the Chip Select Registers. This allows the SPI to automatically adapt the baud
rate for each interfaced peripheral without reprogramming.
Figure 18-7 on page 201
same chip select. Three delays can be programmed to modify the transfer waveforms:
These delays allow the SPI to be adapted to the interfaced peripherals and their speed and bus
release time.
• The delay between chip selects, programmable only once for all the chip selects by writing
• The delay before SPCK, independently programmable for each chip select by writing the field
• The delay between consecutive transfers, independently programmable for each chip select

chip select and before assertion of a new one.
