Its the other way around - SPI doesn't work, when SSEL is configured
as GPIO.
You MUST enable the SSEL function on that pin in order to use SPI.

They even mentioned it in the manual:
"Note: LPC2114/2124/2212/2214 configured to operate as SPI master MUST
select SSEL
functionality on an apropriate pin and have HIGH level on this pin in
order to act as a
master."

LPC2114/2124/2212/2214
USER MANUAL, p. 163

This pin is wasted, if you want to do master mode SPI :-(

Not possible, AFAIK
