Multi-byte 9361 SPI Timing Diagram

Hi,

The 9361 and 9364 Reference Manuals only show the timing waveforms for single SPI write and read.  Can ADI provide the timing diagrams for multi-byte writes and reads?  Or, point me to an equivalent specification on-line?

 

  On page 105 of the 9364 Reference Manual, in the paragraph titled "Example: MSB-First Multibyte Transfer", it says that 16 extra clocks must be provided after the fourth byte and can be used to clock in the next instruction.  If I don't want to clock in the next instruction, do I drive zeros on the SPI_DI for those sixteen clocks?  Or, will bringing SPI_ENB high at the end of those 16 clocks cancel the instruction?  Or, do I just bring SPI_ENB high after the end of the fourth byte.

 

Thanks,

Tom
