The AB926EJ-S User Guide (ARM DUI 0225A) section 3.15 describes the Synchronous Serial Port (SSP) on this board, and implies that the port can be used as a master or a slave. This is misleading, as although the ARM926EJ-S Development Chip supports it, the slave related signals are not routed to the expansion connectors so only 'Master' is supported on the AB926EJ-S.

For reference, the SSP signals available on each type of Versatile baseboard are listed in the following table:

Note that  it is not possible to gain access to the missing SSP signals on the AB926EJ-S PCB by connecting wire jumpers directly to the pads as they exit the chip, since these signals are not connected to vias. If you wish to use a 'Slave' configuration we recommend you use the Versatile/PB926EJ-S.
