Clock Generation
Transfer Delays
SPCK
The SPI Baud rate clock is generated by dividing the Master Clock (MCK) or the Master Clock
divided by 32, by a value between 1 and 255. The selection between Master Clock or Master
Clock divided by 32 is done by the FDIV value set in the Mode Register
This allows a maximum operating baud rate at up to Master Clock and a minimum operating
baud rate of MCK divided by 255*32.
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.

select. Three delays can be programmed to modify the transfer waveforms:
• The delay between chip selects, programmable only once for all the chip selects by writing the
• 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 by
These delays allow the SPI to be adapted to the interfaced peripherals and their speed and bus
release time.
DLYBCS field in the Mode Register. Allows insertion of a delay between release of one chip
select and before assertion of a new one.
DLYBS. Allows the start of SPCK to be delayed after the chip select has been asserted.
