It is a ppc440 but it is does not have ans  spi controller as in the
amcc. The spi controller is a xilinx core allocated at the plb bus,
including a deeper fifo.

The actual version  does not have a sustained speed of 33Mhz but a can
have a peak speed of 33 MHz


               Thanks for your comment
