STM8 SPI Wakeup

I am using the STM8S as an SPI slave device.  The protocol I am using has a fixed sized buffer and I was thinking about using this interrupt to reset the buffer pointers.  The data sheet suggests that this interrupt can be used to wake up the STM8 from wake or halt mode.  Does this mean that it only works in these modes or does it happen every time SPI comms is initiated by the master.

I have tried experimenting with this and it appears to be the case but I'm looking for confirmation before I start to reply on this.

Thanks in advance,

Mark
