Can SSP run at up to 30 Mbps?

Started by croquettegnu March 5, 2007
Hi all,

In theory, max baudrate for the SSC will be CCLK/2/VPBDIV.
So it seems possible to clock the SSP @30MHz.
Is it the case in real life?

Thanks in advance

We did some tests with a fast SPI memory and it did work at 30 Mbit,
however there is an entry in the Errata Sheet which says the first
pulse is a shorter (SSP.1) e.g. in the LPC213x family. This might have
an impact on the max. possible speed.
