Hi

The SSEL is used when the LPC210x is  acting as an SPI slave.
you need to drive the chip selects yourself.

  Subject: [lpc2000] Interfacing two peripherals on the same SPI port... SSEL function?


  Dear, 

  How should I use the SPI port on an LPC2200 processor if I want to
  interface two or more peripherals on it? 

  I thought that every slave peripheral should have a dedicated Chip
  Select signal, and the one for which CS is low would be allowed to
  talk/hear. 

  BUT, there is only one SSEL signal per SPI bus on the LPC. Should I
  use GPIO pins to create a CS for each peripheral? 

  Many thanks in advance.
