SSP is a generic term meaning synchronous serial port, much like
SPI is a synchronous serial port, although SPI was originally made
by motorola. Most processors that state they have SSP also state
that the SSP is flexible, and usually state that the SSP can support
Freescale (Motorola) SPI, Microwire, and TI Synchronous Serial
interfaces. The details on how fast it can transmit and receive will
depend on the silicon and if it has FIFO, how much FIFO etc,
you need to look at the data sheets and manual to understand
the limitations. In general, if it states it has SSP, then it can do the
SPI type communication. To make things even more silly Intel
uses the term NSSP (network synchronous serial port) on the
X-Scale, but when you read the docs it's an SSP like others
that supports SPI, Microwire, and TI synchronous serial.

Hi at All
What is the difference from SPI and SSPI interface?
I can send at receive the data a max speed in SSPI?
What is the max speed in SSPI interface?
In this my application the LPC2364 is the master and driver one slave
SPI I can use the libray function (in Keil) for SPI?
The Irq for receive and transmit the data are the same in SPI interface?
What are the limitation when use the chanel SSPI in emulation SPI?
