Lpc2000

hi,
i need a SPI bus with 15MHZ clock can work for MMC.
i see that the SPI0 for lpc2148 is max to 7.5 MHZ(1/8 PLCK)
& i see that SSP(SPI1) can clock max PLCK/2 so about 30 mhz.
so i want to know can i use SPI1 for MMC. becuse i read it is the 
motorola sPI.
is it any different from normall SPI?


thanks.
