Lpc2000

Hi 
I am using lpc2106 and SPI.
I can't get it to work, it should be simple but..

Here is what I do
//----------------------------------------------
PINSEL0 |= 0x5500;	// enable SPI pins
SPCR     = 0x20;	// set master mode
SPCCR    = 128;		// SCK =pclk/128


SPDR = c;		// start transfer
//-----------------------------------------------

but there is no activity on the  SCLK.

1) Should be SSEL be pull-up ? (it is always low)
How do activate/deactivate SSEL ?
(in the user manual on page 127 is say SSEL is not directly driven by
the master.It could be driven by a simple general purpose I/O under
software control.)
2) Should I still select SSEL as alternate function SSEL or general
purpose I/O ?


Please if any one have used SPI and SSEL, please comment

best regards

John
