Is it really true?
Does the SSP interface has no interrupt for the transmit fifo empty event or for transfer empty? The SPI interface has, but I cannot use the SPI interface because the pins a used from SPIFI.

So in my distress I have to start a timer to get an interrupt at transfer end.
Or as somebody a better idea?
Please don't ask me why I use a transfer end interrupt. This is because a scan several SPI slave and I have to change the select signal by gpio.
