Да. Внятно - ничего, но есть такой документик на сайте Atmel'а - "Using the Serial Peripheral Interface (SPI) with AT91SAMxx Devices" и там есть такой текст: The following figure shows two AT91SAMxx devices exchanging data through the SPI bus.

Clock (SPCK) and selection signals (NPCS) are provided by the Master. The clock has to be compatible with the Slave in terms of waveform (phase and polarity) and speed. In the case where the master addresses an AT91SAMxx device the waveform has no restriction and the maximum operating baud rate is (Slave Master Clock) / 2. (Depending on I/O speeds and setup constraints.)
