Hi,

I'm gonna use one of the three SSP interfaces of the LPC1778.

I need to use it as a SLAVE interface.

The external SSP master has a SSEL signal which works the opposite way:

- it goes high when a data transfer starts

- it goes low when the data transfer ends.



QUESTION
----------------
Is there any way to change the default polarity of the SSEL signal of the SSP interface?



Thanks,
Enrico Migliore
