Is the watermark parameter for CyU3PGpifSocketConfigure (for configuring a partial full flag) only relative to the current buffer, or to all the buffers in the channel as a whole?

That is, if I have the slave fifo DMA channel set up with 2 buffers of 512 bytes, and I specify a watermark at 768 bytes (192 samples for 32-bit mode), will the watermark be hit if one buffer is filled but not consumed, and the second is half-full?  Or does it only consider the current buffer, and such a watermark will never be hit?

We would like to understand this better. Please create a tech support case (MyAccount -> MyCases) so that we can discuss this further.
