SSEL Pin Error

2004-12-13 by Sridhar gadda

Hi, 
        when you configured SPI interface , Master as �c. In manual its return that "LPCconfigured as SPI master MUST select SSEL functionality on an appropriate pin and have HIGH level on this pin in order to act as a master" (page 170)
 
if you configure PINSEL0 = 0x00005500 // selects SCK0, MISO, MOSI and SSLE 
 
but how can we generate HIGH on SSLE pin which is  P0.7..........As far as I know you can only generate HIGH on GPIO pins only if they configured as OUTPUT pins. 
 
             My question is how to generate high on SSLE when it is not configured as GPIO pin.
 
   Any help and suggestions would be appreciated.
 
 Thanks in advance.
 
 With regards,
 
Sridhar
